Where is the 'constr' function located?

Hi,

I'm trying to run some code from Brian Smits: http://www.cs.utah.edu/~bes/papers/color/

And I'm having the following error:

Undefined function 'constr' for input arguments of type 'char'.

The calling code is as follows:

x = pinv(A) *white;
whiteS = x + null(A) * constr('colorFun',zeros(N-3,1),options);

I thought the function was in the Optimization toolbox, but it actually doesn't looks like it.

Cheers,

Thomas

I actually managed to find legacy functions here and there and run the code, we have pushed all that here: https://github.com/colour-science/smits1999

If the following link is talking about the same 'constr', it was replaced by fmincon some time ago

Thanks for that! The function signature is however different, so a dumb search and replace doesn't work unfortunately!

No, but you could write your own constr.m file that acts as a wrapper for fmincon, passing the input data to fmincon in the form that it expects.
