MATLAB: Replace column

image processingMATLAB

How to replace a column with ones in a image containing rows and coulumns with zeros.

% 2D example:
A = zeros(5)
A(:,3) = 1
% 3D example:
A = zeros(3,3,3)
A(:,2,:) = 1

Hi Wael !

H(:,3) = H1(:,1)

This would replace all rows of column 3 of H with all rows of column 1 of H1

H1(:,3) = zeros % making the third column as zeros
H1(3,:) = zeros % making the third row as zeros

These two commands will help you achieve making the dimension of matrix H1 3*3 by adding zeros

 A = randi(10,[10 640])-1;
 B = A;
 B(:,sum(A==0)>0)=0;
