Calculates the curve length of a 1D function between start and end. Details
![]() |
start is the start point of the interval. The default is 0.0. |
![]() |
end is the end point of the interval. The default is 1.0. |
![]() |
formula is a string describing the function under investigation. You can use any valid symbol as the variable name. Refer to Formula VI Variables for valid symbols. |
![]() |
X Values is the array of all regarded points in the interval (start, end). |
![]() |
Curve Length is an array of the values of the curve length of formula between start and end at all X Values. |
![]() |
ticks is the time in milliseconds to analyze the formula and to produce the X Values array and the Curve Length array. |
![]() |
error indicates the accuracy of formula, which is verified by the Function VIs. |
The curve length of a given function f(t) between start and end can be calculated by the following equation.
This calculation is implemented using the Integration VI, which is why the calculations are based on the Runge Kutta method.
