Last Modified: March 15, 2017

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

connector_pane_image
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 points of both variables. The array contains two elements.

datatype_icon

end

End points of both variables. The array contains two elements.

datatype_icon

variables

Variables with respect to the naming conventions of the Parsing nodes.

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

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)
