Evaluating fund performance using Carhart 4 Factor Model

I have been asked to write an essay on mutual fund performance using Carhart's 4 Factor Model using MATLAB.

I have got the information on the total returns of the funds that I wish to assess and the values for the 4 factors of the model off Kenneth French's website, but I am unsure of what I should do now.

Any help would be much appreciated!
