imaginary (img)

The imaginary function strips the imaginary values out of a range of complex numbers.

Syntax

img(block)

The range is made up of complex numbers.

Example

If x = {{1,2,3,4,5,6,7,8,9,10}, {0,0,0,....0,0}}, the operation img(x) returns {0,0,0,0,0,0,0,0,0,0}.

If x = {{1.0,-0.75, 3.1}, {1.2,2.1,-1.1}}, the operation img(x) returns {1.2,2.1,-1.1}.
