y = ifftn(x)
which computes the same-size inverse FFTs for each dimension of x
.
Alternately, you can specify the size vector
y = ifftn(x,dims)
where dims
is a vector of sizes. The array x
is zero padded
or truncated as necessary in each dimension so that the output
is of size dims
. The ifftn
function is implemented by a sequence
of calls to ifft
.
