	Make stk_test() silent as a grave.

	* misc/test/stk_test.m: Use evalc() instead of eval() to make
	stk_test() silent as a grave. Only works in Matlab for the time

2013-03-20  Julien Bect  <julien.bect@supelec.fr>

	Improve stk_runtests().

	* misc/test/stk_runtests.m: Include class directories and private

	* paramestim/stk_remlqrg.m: Add local variables for (slightly)
	improved readability and efficiency.

	Modify stk_remlqrg() to support objects in model.param.

	* paramestim/stk_remlqrg.m: Ensure that param is a column vector;
	in the case where model.param is an object, this is actually a
	call to subsasgn() in disguise.

	Fix a (recently introduced...) bug in stk_param_init().

	* paramestim/stk_param_init.m: Use log10() when calling

	non-empty lognoisevariance field, since its value won't be used.

	Fix other bugs in stk_param_init().

	* paramestim/stk_param_init.m: Remove the second normalization
	that was performed in the internal function paraminit_(). Use the
	correct box diameter to choose the list of range values for
	isotropic covariance functions.

2013-03-13  Julien Bect  <julien.bect@supelec.fr>

	Fix a bug in stk_param_init().

	* paramestim/stk_param_init.m: Remove the value of the regularity
	parameter from param for stk_matercov32_iso and
	stk_materncov52_iso covariance functions.

	Avoid the use of 'stable' with unique().

	* misc/dist/stk_filldist_exact.m: Avoid the use of 'stable' with
	unique() since Octave doesn't currently support it (and we don't
	really need it, anyway, or so it seems).

2013-03-12  Julien Bect  <julien.bect@supelec.fr>

	Check the size of 'box' in stk_normalize.

	* utils/stk_normalize.m: Check the size of 'box' before using
	it. Raise an error if it's not [2 d].

	Return empty from stk_param_estim when lnv is not estimated.

	* paramestim/stk_param_estim.m: Return empty for the second output
	argument when lognoisevariance is not estimated (to avoid warnings
	about output arguments not being assigned).

	computation of stk_quadform() in several special cases.

	* misc/config/stk_compile_all.m: Compile the new MEX-files.

2013-02-26  Julien Bect  <julien.bect@supelec.fr>

	Prepare stk_param_estim for parameter objects (instead of vectors).

	* paramestim/stk_param_estim.m: Prepare for parameter objects. Rename
  	  the optimized vector for 'param' to 'u' for clarity (since it is
	  sometimes an extended parameter vector).

2013-02-10  Julien Bect  <julien.bect@supelec.fr>

	Fix and improve stk_datastruct().

	* utils/stk_datastruct.m: Call inputname correctly, with an input
	argument. Return an empty data structure when nargin == 0. Add
	some tests.

	hidden option to trigger the construction of an extended (N)OLHS
	following the paper by Cioppa & Lucs (Technometrics, 2007).

	Fixed a bug in stk_rescale() and added regression tests.

	* utils/stk_rescale.m: Fixed a bug in the first part of the
	function (i.e., the part where the data is scaled from its
	original box to [0; 1]^d). Added some regression tests.

2013-01-21  Julien Bect  <julien.bect@supelec.fr>

	Modified stk_set_root() to avoid the use of a persistent variable.

	* misc/config/stk_set_root.m: modified. The use of a persistent	variable
	was failing to play its intended role when switching from one version of
	STK to another. The root folder is now detected using which('stk_test').

2013-01-20  Julien Bect  <julien.bect@supelec.fr>

	Fixed a test in stk_filldist().

	* misc/dist/stk_filldist.m: modified test. Added a tolerance in a
	comparison; otherwise the test was failing from time to time
	because of numerical errors.

2013-01-19  Julien Bect  <julien.bect@supelec.fr>

	Added a DoE example (sequential space-filling).

	* examples/02_design_of_experiments/stk_example_doe02.m: new
	script.

	Fixed a numerical issue in stk_filldist_exact().

	* misc/dist/stk_filldist_exact.m: modified. Because of possible
	numerical inaccuracies, centers that are slightly outside the box
	must also be considered as candidates for being ymax.

	Fixed a bug in stk_filldist().

	* misc/dist/stk_filldist.m: modified. Fixed a bug in the
	discretized case (the second output argument was the index of ymax
	instead of ymax itself, as advertised by the documentation).

	Added tests to all fill distance-related functions.

	* misc/dist/stk_filldist_exact.m: added tests.
	* misc/dist/stk_filldist_discretized.m: added tests.
	* misc/dist/stk_filldist.m: added tests.

	Added a second output argument to stk_filldist_discretized().

	* misc/dist/stk_filldist_discretized.m: modified. The function now
	returns, as a second output argument, the point where the maximum
	distance is attained, as expected by stk_filldist().

2013-01-17  Julien Bect  <julien.bect@supelec.fr>

	Completed the documentation of stk_fill_dist and
	stk_filldist_discretized.

	Computing, 2011).

	* misc/dist/stk_filldist.m: replaced
	* misc/dist/stk_filldist_discretized.c: formerly stk_filldist.c

	variable OCTAVE_VERSION to check if running under Octave (instead
	of calling ver(), which was not working properly with some old
	versions of the miscellaneous package).
	* stk_init.m: idem.

	Miscellaneous changes.

	* sampling/stk_mindist.c: removed unused variable lambda in
	  stk_mindist.c

2012-02-06  Julien Bect  <julien.bect@supelec.fr>

	Fixing bugs and comments in covariance functions.

	* covfcs/stk_materncov52_aniso.m: Fixed a bug (an old function
	name was still used) and some comments.
	* utils/specfun/stk_sf_matern52.m: Fixed missing abs() in
	stk_sf_matern52(). The result was wrong for negative arguments.
	* covfcs/stk_materncov_aniso.m: Fixed comment.
	* covfcs/stk_materncov_iso.m: Fixed comment.

2012-02-05  Julien Bect  <julien.bect@supelec.fr>

	New covariance function (Matérn 5/2).

	* utils/specfun/stk_sf_matern52.m: New function.
	* covfcs/stk_materncov52_aniso.m: New function.
	* covfcs/stk_materncov52_iso.m: New function.
	* core/stk_param_estim.m: Added Matérn 5/2 to get_default_bounds().
	* examples/example06.m: New script.
	* examples/run_all_examples.m: Increased NB_EXAMPLES.

	Fixed issues in stk_param_estim.m related to the definition of the
	search domain and the selection of (constrained/unconstrained)
	optimizer.

	* core/stk_param_estim.m: Enlarged the search domain in such a way
	that param0 is always inside it. Changed the selection of
	optimizer to use fminsearch when either the upper- or the
	lower-bound are empty. Moved the definition of the 'options'
	struct to the Matlab-specific part of the code.

	Miscellaneous changes.

	* examples/example02.m: Doc & code formatting.
	* utils/plot/stk_plot1d.m: Added an optional argument to allow
	plotting on an existing axis.

	New directory for special functions (./utils/specfun).

	* utils/specfun: New directory.
	* utils/config/stk_set_root.m: Added ./utils/specfun to the path.
	* covfcs/stk_materncov_.m: Removed.
	* utils/specfun/stk_sf_matern.m: Replacement for stk_materncov_.
	* covfcs/stk_materncov_aniso.m: Modified to use stk_sf_matern.
	* covfcs/stk_materncov_iso.m: Modified to use stk_sf_matern.

2012-02-02  Julien Bect  <julien.bect@supelec.fr>

	Miscellaneous changes.

	* README.txt: Improved requirements and recommendations.
	* core/stk_param_estim.m: Clarified selection of optimizer.

	Improved handling of Octave packages.

	* utils/stk_check_octave_packages.m: New function to check
	for required packages under Octave.
	* stk_init.m: Added a call to stk_check_octave_packages(). Removed
	some left-overs from an earlier version of stk_init where
	fminsearch() was used instead of sqp() under Octave. Moved call to
	stk_is_fmincon_available() to the Matlab-conditional part.

	Fixed a parsing problem occuring in Octave 3.4.3 (at least),
	related to the fact that parfor loops are supposed to end with an
	"endparfor" instead of a simple "end"... but we don't use "parfor"
	at all if we are running in Octave.

	* core/stk_make_matcov.m: Moved some sub-functions to independent
	M-files stored in a private sub-folder.
	* core/private: New folder.
	* core/private/stk_make_matcov_auto_parfor.m: New file (the code
	in this file was previously part of stk_make_matcov.m).
	* core/private/stk_make_matcov_inter_parfor.m: New file (the code
	in this file was previously part of stk_make_matcov.m).

2012-02-01  Julien Bect  <julien.bect@supelec.fr>

	Minor bugfix + improved error message in stk_remlqrg()

	* core/stk_remlqrg.m: Minor bugfix: returns nan for the derivative
	with respect to the noise variance in the case of a model without
	observation noise.  Improved error message if NOISEPRIOR &&
	~NOISYOBS (doesn't use assert anymore).

	* core/stk_remlqrg.m: minor bugfix + improved error message in
	  stk_remlqrg()

	Added a script to run all the examples and report on errors.

	* examples/run_all_examples.m: new script
	* examples/example0*.m: remove "clear all; close all;"

	Improved script stk_init.

	* utils/config/stk_set_root.m: new function
	* utils/config/stk_get_root.m: new function
	* utils/config/stk_compile_all.m: new function
	* stk_init.m: Modified to use the new functions. Also, added a
	'clear' statement for temporary variables STK_ROOT, fmincon_found,
	octave_in_use, s and ans at the end of the script.

	Created subdirectories in ./utils.

	* utils/config: new subdirectory
	* utils/stk_is_fmincon_available.m: moved to ./utils/config
	* utils/stk_is_octave_in_use.m: moved to ./utils/config
	* utils/stk_is_pct_installed.m: moved to ./utils/config
	* utils/plot: new subdirectory
	* utils/stk_plot1d.m: moved to ./utils/plot
	* utils/stk_plot1dsim.m: moved to ./utils/plot

	Moved stk_feval to ./core (where it should always have been).

	* utils/stk_feval.m: moved to ./core
