# Spike Function (G Dataflow)

Version:

Generates the spike function for any real number.

## x

A real number.

## error in

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

Default: No error

## spike(x)

Value of the spike function for the given value of x.

## error out

Error information. The node produces this output according to standard error behavior.

## Algorithm for Calculating the Spike Function

The following equation defines the spike function:

$\mathrm{spike}\left(x\right)=\left\{\begin{array}{cc}1& \text{if}0\le \text{x}<1\\ 0& \text{elsewhere}\end{array}$

The following illustration shows the graph for spike(x) - spike(-x) in the interval (-4.0, 4.0).
