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
