Hi, I have a set of scattered data and I can use the operator "\" to do a linear fit on the data. But is there a simple matlab function to get the R^2? I am trying to skip the calculation shown on page: https://www.mathworks.com/help/matlab/data_analysis/linear-regression.html
BTW, I don't have machine learning toolbox.
Thanks for any help. If there is no simple matlab function, then I will have to try to calculate by using the sample code shown on the above page.
