Seems like using the MATLAB solvers with MCR requires my wrappers containing in several files to be compiled with MATLAB Compiler before. I have no license for MATLAB thus I may have problems if I'll make it done and will spread it with OpenOpt suite code, also, binary files are incompatible with BSD license. <br><br>Darn, knew it was too good to be true. ? On the other hand, IIRC a little bit obsolete MATLAB versions (I don't think difference is essential) have more liberal licenses. <br>As for MATLAB solvers examples, I have already mentioned them in the mail list, you could see them in <a href="http://openopt.org/ODE">http://openopt.org/ODE</a> (just replace solver name from scipy_lsoda to ode23s or any other), <a href="http://openopt.org/NLP">http://openopt.org/NLP</a> , <a href="http://openopt.org/SNLE">http://openopt.org/SNLE</a> <br>Oooops, so sorry. :-o? <br>DG? <br>---------------------- <br>Regards, D. <a href="http://openopt.org/Dmitrey">http://openopt.org/Dmitrey</a> <br>-------------- next part -------------- <br>An HTML attachment was scrubbed... <br>URL: <a href="http://mail.scipy.org/pipermail/numpy-discussion/attachments/20131005/dd6638db/attachment-0001.html">http://mail.scipy.org/pipermail/numpy-discussion/attachments/20131005/dd6638db/attachment-0001.html</a> <br><br>------------------------------ <br><br>_______________________________________________ <br>NumPy-Discussion mailing list <br><a href="mailto:NumPy-Discussion@scipy.org">NumPy-Discussion@scipy.org</a> <br><a href="http://mail.scipy.org/mailman/listinfo/numpy-discussion">http://mail.scipy.org/mailman/listinfo/numpy-discussion</a> <br><br><br>End of NumPy-Discussion Digest, Vol 85, Issue 17 <br>************************************************ <br><br><br><br>-- <br><blockquote type="cite">From "A Letter From The Future" in "Peak Everything" by Richard Heinberg: <br></blockquote><br>"By the time I was an older teenager, a certain...attitude was developing among the young people...a feeling of utter contempt for anyone over a certain age--maybe 30 or 40.?
