DESCRIPTION

Function normal normalizes a matrix M to occupy lower-upper range. The intent of this function is to be a shortcut to a simple but often used operation.
N = normal(M) normalizes N to 0-1 range.
N = normal(M,upper) normalizes N to 0-upper range.
N = normal(M,lower,upper) normalizes N to lower-upper range.

EXAMPLE

initial_dir = PWD;
chdir (SIPDIR + 'images');

Img = gray_imread('gra.jpg');
mini(Img)
maxi(Img)
N = normal(Img,255);
mini(N)
maxi(N)

chdir(initial_dir);
