save values of matrix in indexes of another matrix

hello, i want to

  nimg=1;
                for ii=1:imglen
                    for iii=1:c-4+1

                             hashTable(Idximgseq(ii,iii)+1,nimg)={[ii,iii]};
                             nimg=nimg+1;
                    end
                end

save matrix of values in another matrix,such that each value in the first matrix saved in the same value of index in the second matix,but i have a problem that the counter increses in all times,i want to increse the counter in saparete index,such that:

first matrix(1,1)=15 saved in the index 15 colomn 1 in the second matrix,first matix(1,2)=15 saved in the index 15 colomn 2 in the second matrix,first matrix(1,3)=13 saved in the index 13 colomn 1 in the second matrix, but my problem that first matrix(1,3)=13 saved in the index 13 colomn 3 in the second matrix not in the index 13 colomn 1??
