MATLAB: What does the “stats” output from the REGRESS function mean in Statistics Toolbox 5.0.2 (R14SP2)

Statistics and Machine Learning Toolbox

When looking at the documentation for the REGRESS function by typing "doc regress" at the MATLAB prompt, it shows the syntax:
[b,bint,r,rint,stats] = regress(y,X)
In explaining the "stats" vector, it simply says "the vector stats contains the R2 statistic along with the F and p values for the regression." I would like a more detailed description of this vector.

stats = [r2 F prob s2];
