bifft
"Block" Inverse Fast Fourier Transform (IFFT)
Syntax
AF = bifft(A,q)
Arguments
See also Common variable names and data structures.
input
A n1 x n2 x p matrix q frequency resolution (default: p)
output
AF description
Description
Returns the q-point discrete inverse Fourier transform AF of each component vector of the n1 x n2 x p matrix A, where the last index is the vector index. If q < p a warning is issued that the IFFT will truncate.
