remove duplicate rows in sparse matrix
The SORTROWS command seems to accept SPARSE matrix, but it is very slow possibly because of slow ROW accessing I mentioned earlier. In any case, I dig out one of my implementation of HEAPSORT below. With this code you could have few more possibilities to play around with (reverse column/row, inplace mex implementati... 10 Jul 2010 07:17

identification toolbox transfer function
Hi i want to identify the parameters of a transfer using the identification toolbox. My transfer function is characterized by 3 real zeros and 2 couples of complex conjugate poles. In the identification toolbox, i can choose at most a transfer function with 1 zero and 1 complex conjugate pole. Is there a way to inse... 14 Jul 2010 05:30
