Quaternion Function Reference

fftflip2

Reverse signal or spectrum in two dimensions.

Syntax

Y = fftflip2(X)

Description

fftflip2 carries out the two-dimensional equivalent of the operation implemented by fftflip, reversing rows and columns. Like the one-dimensional function, it will work on any type of array, including double, so it may be used on complex arrays.
