MATLAB: Error using optimoptions (line 124)

Question

I am getting the error message mentioned in the title while executing following line

opts = optimoptions('fmincon','Algorithm','interior-point');

I tried setting the default path through

restoredefaultpath
savepath
rehash toolboxcache

Still getting the same error. Can someone help?

Thanks

%if true
  % code
% end
opts = optimoptions(@fmincon,'Algorithm','interior-point');

Try function handle for passing solver name
