MATLAB: How to compile in a matrix

image processingmatrix

clc;
clear all;
a=imread('4.1.05.tiff');
hsv=rgb2hsv(a);
v=hsv(:,:,3);
for p=1:256
for x=v(1:256, p);
h=imhist(v);
a=sum(x.*h);
b=sum(h);
M=a/b;
C1=1:1:M-1;
C2=M-1:M:256;
q=1-((M-x))
end
end
in this code value of q is of (matrix 256*1). after running the code i am getting value of q 256 time (i.e q(matrix 256*1) 256 times). so how can i compile these value to make q of matrix 256*256

Best Answer

q(:,p)=1-((M-x))
