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

    datatype_icon

    number of points

    Numbers of values for both variables used in the function calculation.

    datatype_icon

    formula

    Function definition of exactly two different variables. The formula can contain any number of valid variables.

    Entering Valid Variables

    This node accepts variables that use the following format rule: variables must start with a letter or an underscore followed by any number of alphanumeric characters or underscores.

    datatype_icon

    start

    Start values of the variables in the interval where this node starts calculating values.

    This input can contain only two elements. Otherwise, this node returns an error.

    Default: [0.00, 0.00]

    datatype_icon

    end

    End values of the variables in the interval where this node stops calculating values.

    This input can contain only two elements. Otherwise, this node returns an error.

    Default: [1.00, 1.00]

    datatype_icon

    variables

    Names of the variables.

    Variable names must start with a letter or an underscore followed by any number of alphanumeric characters or underscores.

    datatype_icon

    error in

    Error conditions that occur before this node runs.

    The node responds to this input according to standard error behavior.

    Standard Error Behavior

    Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

    error in does not contain an error error in contains an error
    If no error occurred before the node runs, the node begins execution normally.

    If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

    If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

    Default: No error

    datatype_icon

    exclude end

    Boolean that specifies whether this node uses the end value of the interval when calculating function values.

    True Does not use the end value when calculating function values.
    False Uses the end value when calculating function values.

    Default: False

    datatype_icon

    x1 values

    1D array of the used x1 arguments.

    datatype_icon

    x2 values

    1D array of the used x2 arguments.

    datatype_icon

    y values

    2D array of the calculated function values.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    The illustration below shows the visualization of the following function in the interval (-2, 2) * (-2, 2).

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

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

    Web Server: Not supported in VIs that run in a web application
