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.
