'statsfminbx' issue with user-defined factoran()

Hi

While using

factoran(X,2) ; %where X <250*10>double

I keep getting the following error:

Undefined function 'statsfminbx' for input arguments of type 'cell'.
Error in factoran (line 269)
    [Psi1, nll, lagrange, err, output] = ..

Could someone assist in debugging this please? as i do not see why this error occurs even after looking into line 269.

Thanks

Did you make a copy of factoran.m outside the Statistics and Machine Learning Toolbox directory? That's not going to work; delete that copy and use the copy inside the toolbox directory.

fair enough, I could not figure out since the error message was leading me "somewhere else". I confirm that your suggestion does work. Thanks a lot.
