Special selecting rows of a matrix

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.
