Dear All, I have an original matrix called M that is 1000*15, I extracted a matrix from it based on a condition and is called Tand, Tand is 400*15, now how can i delete the extraced rows from the original matrix? i wrote this but it didnt work, because the size of M is still 1000*15 instead of 600*15 !! please help
Tand= M(M(:,15)<6, :); % this is the extracted one with 400*15 dimension.
M(Tand, :)= []; %this is to delete all the rows from M that belongs to Tand.
%where is the problem?

x = M(:,15)<6; % Remember the logical indexes of the rows
Tand= M(x, :); % this is the extracted one with 400*15 dimension.
M(x, :)= []; %this is to delete all the rows from M that belongs to Tand.

Can you show a short code snippet of what you are trying to do with the files?
