Hi. I have a matrix of size m*n.
I want to select those rows of this matrix that their value in 10th column are between 10 to 12.
How can I do that?
Thanks a lot.

Let M be the given matrix. Then do this:
p = (1:size(M,1)).';
p = p(M(:,10)<=12&M(:,10)>=10);
p will be a column vector consisting of the row indices of all rows in M in which the element of the 10th column lies between 10 and 12.
