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

You can integrate an arbitrary set of parameters in the formula.

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

Function to calculate that contains the variables and parameters. 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.

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]

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]

Names of the variables.

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

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.

**Default: **No error

Variables and their corresponding values in the parameters.

Name of the parameter that uses the conventions of the Parsing nodes.

**Default: **Empty string

Value of **variable**.

**Default: **0

1D array of the used *x*1 arguments.

1D array of the used *x*2 arguments.

2D array of the calculated function values.

Error information.

The node produces this output according to standard error behavior.

Standard Error Behavior

**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.

The following equation is a common function in *x*1 and *x*2:

*f*(*a*, *b*, *x*1, *x*2) = *a* * sinc(gamma(*x*1 + *x*2)) - *b* * sin(*x*1) * cos(*x*2) with *a* = 1 and *b* = 2

You enter only the right side of this equation in **formula**:

a*sinc(gamma(x1 + x2)) - b*sin(x1) *cos(x2)

You enter the values of variables *a* and *b* in **parameters**:
