How can I get F and p-value after regression?

After using the command lsline I got the the regression line that I wanted! But How can I see the statistics of the regression?How do I get the F and P-values?

The lsline function does not give you any information on the fit.
It even takes a bit of effort to get the slope and intercept:
figure(1)
scatter(1:10, rand(1, 10))
hl = lsline;
B = [ones(size(hl.XData(:))), hl.XData(:)]\hl.YData(:);
Slope = B(2)
Intercept = B(1)
You need to use the Statistics and Machine Learning Toolbox regress function to get the information you want.

You need to pay for it first. It is not part of basic MATLAB. Or you can do the computations yourself. But that requires an understanding of those computations.
