N largest elements matlab

I am having a trouble with coding in matrix. I have a matrix P with n x m dimensions.. I need to find the first largest N (less than n) elements from the P and flag them to Let the matrix be Y, where Y(i,j)=1 or 0. Constraint: max(sum(Y(i))=1 ; min(sum(Y(i))=0 Application - I have n number of customers list and m number of offers. If A is a vector, then mink returns a vector containing the k smallest elements of A. If A is a matrix, then mink returns a matrix whose columns contain the k smallest elements of each column of A. If A is a multidimensional array, then mink returns the k smallest elements along the first dimension whose size does not equal 1. You can find good answers to matlab questions also on matlabcentral. I found a good mex implementation there while searching for the same thing. It is done by Bruno Luong using a partial quick-sort algorithm implemented with C-MEX. The complexity is O(n + rouwverzen.net(k)), where n is the size of the array, and k is the number of elements to be selected.
