Have you tried to create your arrays with the numpy.zeros functions rather than the scipy.zeros functions?<br>I can imagine that something may get confused here. Maybe some version mismatch or what not.<br><br>Mark<br><br>

<pre>The matrices are initially created by these lines:

        matout=scipy.zeros((n,n),dtype=complex128)#+0j
        colout=scipy.zeros((n,1),dtype=complex128)#+0j</pre>
