MATLAB: How to subtract columns for each row by using a for loop

Question

Hi,

I have a matrix like this:

[1.011  1.004  1.054
1.008  0.998  1.042
0.984  0.988  1.024
1.026  1.006  1.016
1.000  0.996  0.977]

I would like to subtract each column for each row and store these results in a new matrix. How can I do this?

Thanks!

Answer 1

nk=nchoosek(1:size(x,2),2);
dx=zeros(size(x,1),size(nk,1));
for i=1:size(nk,1)
  dx=x(:,nk(i,2))-x(:,nk(i,1));
end
