I'm looking for the model pvalue in comparison to the constant interception, not the variable pvalues. Thanks

I had the same question. While looking for the answer online, I found the answer to this from here: StackOverflow.
This would work for fitlm as well:
p = coefTest(mdl);
I'm using Matlab 2018a. Not sure if the function is available in previous versions.
Best.

And to get the f-statistic too,
[p,f] = coefTest(mdl);

This answer may come a bit late, but at least it can help people that google the same problem (like me):
The p-value of the F-statistic vs. constant model (for the fitglm) can be retrieved like this:
pVal = RL_Model.devianceTest.pValue;

This works (Matlab 2015b):
load hald
M=fitlm(ingredients,heat)
T=anova(M,'summary')
F=table2array(T(2,4))
pValue=table2array(T(2,5))
