[Coin-ipopt] a question about IPOPT

[zwerhu]

Hi, Dr. Hauan,      When I used IPOPT to solve a NLP, there're some errors which I attached in the attachment. The constraints contained some sines of the variables, and I didn't know whether this has something to do with the error. Please have a look at it. And would you please tell me how to solve it? If necessary, must I send you the matlab files that I wrote? I didn't know whether there're some bugs about the package. Thanks a lot!                                Howard
