File Information
Description

Performs Multivariate Polynomial Regression on multidimensional data. The fits are limited to standard polynomial bases with minor modification options. Feel free to implement a term reduction heuristic.
The functionality is explained in hopefully sufficient detail within the m.file. Feel free to post a comment or inquiry.
No longer requires ANY additional toolboxes!
Head over to http://ahmetcecen.github.io/MultiPolyRegress-MatlabCentral/ or the GitHub page on the right for a full illustrated tutorial. You can also publish Example.m for the same purpose.

An oversight. Will fix it when I get a chance.

To suppress output that may not be required, please add a semicolon to the expression in line 173.
eval(['PolyExp = ',variablesexp,Poly,';']);

Fast and easy to use. MATLAB lacks such a function in its original releases.

Excellent code, I have been looking for multivariate polynomial regression tools for quite some time.

If you send me (it's very easy to find my contact information online, including my profile here) the data and parameters to replicate your situation, I can look into it. Otherwise very hard for me to search for a random bug.

Hi Thanks for the function.I have tried your function with my seven independent and one dependent variable and R-squared is 0.19 which is not high.How can I get higher R-squared ?I also got error when I used 'range'.Any suggestion would be appreciated in advance.

Hi, I tried to use the function but I have a lot of NaNs in my data. It looks like it cannot handle data with NaNs. Could you please update to include NaNs?
