22 Oct 2002 (Updated )

Case study used in Biomedical and Image Processing seminars (highlights algorithm development).

[x,y]=limits(a)
function [x,y]=limits(a)
% LIMITS returns min & max values of matrix; else scalar value.
%
%   [lo,hi]=LIMITS(a) returns LOw and HIgh values respectively.
%
%   lim=LIMITS(a) returns 1x2 result, where lim = [lo hi] values
