rejection method

Hey all,

i created a 2xn matrix where the first row indicates time uniformly distributed... However i want to delete from the matrix columnwise if in the first row the time takes the value 0. i tried to do this using an if algorithm however it seems to reject all values and i end up with an empty matrix. does anybody know how to fix this?

Thanks for your help!

Firstly, it would probably be more efficient to use a .<nx2> matrix. Matlab is column oriented.

Try

    M( :, M(:,1)==0 ) =[];
