# Scaling and Mapping (Map Table » 2D Array) (G Dataflow)

Last Modified: January 12, 2018

Scales a signal by using a two-dimensional array as the table scale.

## signal

Input signal.

This input accepts the following data types:

• Waveform
• 1D array of waveforms
• Double-precision, floating-point number
• 1D array of double-precision, floating-point numbers
• 2D array of double-precision, floating-point numbers

## table map

Two-dimensional array used for scaling.

## 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

## scaled signal

Result of scaling the input signal.

This output can return the following data types:

• Waveform
• 1D array of waveforms
• Double-precision, floating-point number
• 1D array of double-precision, floating-point numbers
• 2D array of double-precision, floating-point numbers

## error out

Error information.

The node produces this output according to standard error behavior.
