What version of Matlab has the "polyfix" function?

I am aware there is a Matlab function "polyfix" used to constrain certain points for least square polynomial fit. Please, does anyone know what version of Matlab that has this function? Thank you.

Thank you @Walter. I have actually seen that, but was wondering how on earth to apply it. Does it mean i have to save the function and then call it in my code? Also, am sure there will be need for edit?

For the version it was written for it says "MATLAB release MATLAB 8.0 (R2012b)" and will probably work for later versions, assuming it uses no deprecated functions that have since been removed.

You need to download it and unzip it to a folder, like a new folder called polyfix. The use SetPath on the Home tab of the tool ribbon to add it to your search path. Then you can call it following directions and examples in the polyfix code.
