## Name

imult — multiplication by i the imaginary unitary

## Calling Sequence

y=imult(x)

## Parameters

- x
real or complex scalar, vector or matrix

- y
complex scalar, vector or matrix

## Description

`imult(x)`

is a more efficient way to multiply x by
i than y = %i*x, without the problems occuring when x comprises "special"
floating point numbers as %inf and %nan.

## Examples

z1 = imult(%inf)
z2 = %i * %inf
