Eval y=f(x1,x2) (Not in Base Package)

Calculates a 2D array of function values defined on a grid. Details

number of points describes the number of grid points for both variables. The default is 25.
Start are the start points of both variables, that is, an array of length 2. The default values are (0,0).
End are the end points of both variables, that is, an array of length 2. The default values are (1,1).
formula is a string representing a function definition of exactly two different variables. The naming conventions of the Formula VIs are valid. Refer to Formula VI Variables for more information about valid variables.
Variables is an array of two strings representing the two variables with respect to the naming conventions of the Formula VIs. The default variables are (x1, x2). Refer to Formula VI Variables for more information about valid variables.
X1 Values is a 1D array of the used x1 arguments.
X2 Values is a 1D array of the used x2 arguments.
Y Values is the resulting 2D array of the function values.
error returns any error or warning condition from the VI.
ticks is the time effort for the whole calculation of the function values in milliseconds.

The following diagram shows the visualization of the function

f(x1, x2) = sin(3*x1) * cos(3*x2)

in the interval

(–2, 2) × (–2, 2).
