<p class="MsoNormal">Dear Sir,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am using the ts solver to solve a set of ODE and DAE. The Jacobian matrix is a 1152 *1152 sparse complex matrix.<o:p></o:p></p>
<p class="MsoNormal">Each TSStep in TSSolve is taking nearly 1 second. Thus, I need to improve the speed of TSSolve.<o:p></o:p></p>
<p class="MsoNormal">Which parts should be taking into account to accelerate TSSolve?
<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Thank you very much.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Regards<o:p></o:p></p>
