Inputs/Outputs

  • cu32.png number of points —

    number of points describes the number of grid points for both variables. The default is 25.

  • c1ddbl.png Start —

    Start specifies the start points of both variables, that is, an array of length 2. The default values are (0, 0).

  • c1ddbl.png End —

    End specifies the end points of both variables, that is, an array of length 2. The default values are (1, 1).

  • cstr.png formula —

    formula is a string representing a function definition of exactly two different variables. The formulas can contain any number of valid variables.

  • c1dstr.png Variables —

    Variables is an array of two strings representing the two variables with respect to the naming conventions of the Formula Parsing VIs. The default variables are (x1, x2).

  • i1ddbl.png X1 Values —

    X1 Values is a 1D array of the used x1 arguments.

  • i1ddbl.png X2 Values —

    X2 Values is a 1D array of the used x2 arguments.

  • i2ddbl.png Y Values —

    Y Values is the resulting 2D array of the function values.

  • ii32.png error —

    error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

  • iu32.png ticks —

    ticks is the time effort for the whole calculation of the function values in milliseconds.

    • The following illustration shows the visualization of the function

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

    in the interval

    (–2, 2) × (–2, 2).
