<P>you may set maxfct ( maximum #of factors with identical sparsity structure) accordingly your case, make symbolic factorizations only once and then do numerical factorization maxfct times. we have a couple of examples show these cases. </P>

<P>Hi</P>
<P>If the logical structure (not actual values) of the matrix remains same, is there a way to avoid symbolic factorization stage for problems requiring large number of of linear system solutions?</P>
<P>Regards</P>

<P>Could you please direct me to an example to achieve this?</P>
<P>My problem involve solving many linear systems (to obtain solution to non linear system)</P>
<P>For example, I would like to solve</P>
<P>A1 x1 = b1</P>
<P>then</P>
<P>A2 x2 = b2</P>
<P> </P>
<P>where A2 depends on x1, but the sparsity of A1 and A2 are the same (however I do not have A2 until I solve for x1)</P>
<P>Regards</P>
