Optimization Toolbox - Use of 'interior-point'
显示 更早的评论
I have the following code:
options = optimoptions(@fmincon,'Algorithm','interior-point');
f = @(x)CA_OptP(x,DistancesKM, StudentsByTown, A_Students);
[x, fval, output] = fmincon(f,x0,[],[],[],[],0,10, nonlcon, options);
[P_Students, Weights] = CA1(x,param1, param 2)
I get this error message: Undefined function 'optimoptions' for input arguments of type 'function_handle'.
What did I do wrong with specifying options?

You should learn to format your code using the "{} Code" formatting icon, as I have now done for you.

Are you sure you don't mean
options = optimset('Algorithm','interior-point');
Otherwise, where did you encounter the "optimoptions" command?

Hi Christoph and Matt J,
optimoptions is a new class in R2013a meant to be used in place of optimset. If you are not using R2013a it will not be available.
If you are using R2013a and getting that error message, there are a few possible causes:
- You do not have a license for the Optimization Toolbox. You could test this by running the following and see if it is followed by "Has no license availabe"
which -all optimoptions
- The path is corrupted. Run the following:
restoredefaultpath; rehash toolboxcache;savepath
