sfrmat is a Matlab function that provides a spatial frequency response* (SFR) from a digital image f

function out = isarray(a)
% out = isarray(a)
% isarray: true if the variable is an array (>1-dimension), false if not
%
% usage: ret = isarray(v)
%
% arguments:
%     a    = variable.
%     out = 1 if a is a 2-dimensional or higher
%         = 0 if not

dim = size(a);

if min(dim) > 1;
 out=1;
else
