Eval Parsed Formula Node (Not in Base Package)

Separates the parsing process from the evaluating process of the Eval Formula Node VI and improves the runtime behavior of a program containing the Eval Formula Node VIs at different locations. Details

Input Values is an array of numbers, each of which corresponds to the value that is given to each of the variables. These variables can be input in the Variables Input control of the Parse Formula Node VI. The coded form of these variables is available in the Variables input decode parameter of the Parsed Formula Node cluster.
You can wire the Parsed Formula Node cluster directly from the corresponding output of the Parse Formula Node VI. Refer to the Parse Formula Node VI for more information. Parsed Formula Node is a cluster containing the following parameters.
Y Values is a 2D array of numbers representing a storage of detected and analyzed numbers of formula of the Parse Formula Node VI.
Tables is a 3D array with 3 columns. The first column contains a code that stands for the operator, the other two contain codes that stand for the operands.
Variables input decode is the intermediate and coded state of Variables Input.
Variables output decode is the intermediate and coded state of Variables Output.
error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurs before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE.
code is the error or warning code. The default is 0. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
Output Values is a 1D array of numbers corresponding to Variables Output Decode, Y Values, and Tables.
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
code is the error or warning code. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.

Eval Parsed Formula Node Details

This VI has a direct connection from the Parse Formula Node VI and completes an Eval Formula Node VI calculation. You can wire the Parsed Formula Node input of this VI directly from the Parsed Formula Node output of the Parse Formula Node VI.
