wcodemat

Matrix Coding

Calling Sequence

M=wcodemat(X,[MAX],[mode],[abso])

Parameters

X
: input double matrix
MAX
: maximun integer
mode
: row-wise ('r' or 'row'), column-wise ('c' or 'col') or matrix coding ('m' or 'mat')
abso
: non-zero for absolute value coding, zero for original value coding
M
: coded integer matrix with value ranging from 1 to MAX.

Description

wcodemat is an utility of coding for displaying matrix. With coding scheme to specific colormap, the content matrix could be in pseudo-color.

Examples

x=rand(100,100);
m=wcodemat(x,64);
cmap=jetcolormap(64);
y=ind2rgb(m,cmap); // function provided by SIP toolbox
imshow(y); // funtion provided by SIP or SIVP toolbox
