MATLAB: The system function ‘fmincon’ calls function ‘sfminbx’, but it shows error such as Undefined function ‘sfminbx’

Question

the system function 'fmincon' calls function 'sfminbx', but it shows error such as Undefined function 'sfminbx'. I want to know any other matlab toolbox contain 'sfminbx'? or any other problem? I am looking forward to your early reply.

Answer 1

It appears to be a function private to the Optimization Toolbox. fmincon() is also part of that toolbox. Try reinstalling that toolbox.
