From: Fatnassi on 12 Jun 2010 07:54 Hi everybody, I´m looking for a compact way to localize a row in a matrix deleting that row and reshaping the matrix..! to a new one without the found row..! The problem is has to be compact cause it will be a part of a very long script with GUI and i have to spare some ram ...so solution with loops ...will not solve my problem.. Thunks..!

Hi Fatnassi, The best way depends on the entries in the matrix. For example, find() may work well in some instances and not in others. I think you should give us a little more detail on what characteristics the particular row has, or rows have, that you wish to delete. Wayne

I just need to delete a row from a matrix...! so this is what i meant.. : x=[l c] M=[1 2;5 7;46 44;45 35] x is of course a variable vector and i want to find out if that row is defined in my matrix M and if yes than delete it and reshape the matrix M..! Thunks!
