function f=shpf(x,m,n)
%SHPF   Reshape matrix into MVFR matrix
%       SHPF(X,m)  reshapes the columns of X into an MVFR matrix
%       with square component matrices m-by-m.
%       X is a matrix with one column per element of the MVFR matrix
%       and one row per frequency. Each row is reshaped into a
%       component matrix using A(:) where A=eye(n).
%
%       SHPF(X,m,n) reshapes the rows of X into component matrices
%       with m rows and n columns.
%
%       SHPF(X,A) reshape the row of X into component matrices the
%       same size as A.
