Hello, i am trying to declare this nonlinear constraint in opti toolbox using scip solver. I just want to ask if there is an alternative command for 'find'
nlcon3= @(x) [x(9*N+(find(x(9*N+1:10*N),1,'first')))* x(9*N+(find(x(9*N+1:10*N),1,'first'))+1)*x(9*N+(find(x(9*N+1:10*N),1,'first'))+2)*x(9*N+(find(x(9*N+1:10*N),1,'first'))+3)*x(9*N+(find(x(9*N+1:10*N),1,'first'))+4)];
nlrhs3 =1;
nle3 =1;
Thank you for your support.

nlcon3= @(x) product(x((0:4) + x(9*N+(find(x(9*N+1:10*N),1,'first')));

Instead of using an anonymous function, you could write that into its own function file and then only call find once, assign the output to a variable and use that variable a few times.

I see no evidence that "find" is not compatible with opti toolbox. I do see evidence that it did not work the way you called it. It would have been easier on us if you had given us the same information you gave the OPTI forum in https://groups.google.com/forum/#!topic/opti-toolbox-forum/14YggFfG11s namely that you get an error
Undefined function 'find' for input arguments of type 'scipvar'.
and that
(Remember SCIP only supports a subset of MATLAB commands)
Rather than having us guess about what SCIP does support, you should post a link to that information.
