Question

Through help from users on this site I have come to the following to remove columns from matrix:

a = [5 1 4; 2 1 1; 5 2 8];
n = size(a,1)
for i=1:n,  
    [v, i] = min(a(3,:));
    col = a(:, i);
    a(:, i) = [];
end

I am looking to combine the col for each of the iterations to one matrix.

Any suggestions?

I’m not quite sure if I understand the question. Do you want this:

a = [5 1 4; 2 1 1; 5 2 8];
n = size(a,1);
result = [];
for i=1:n
    [v, i] = min(a(3,:));
    col = a(:, i);
    result = [result col];
    a(:, i) = [];
end

The result would look like:

 1     5     4
 1     2     1
 2     5     8
