I want to calculate the % of variance explained by each variable in a GLM, for that I need the summ of square. Can we get it from the fitglm function output ?

You can get SST, SSE and SSR:

mdl = fitglm(rand(100, 2), randi([0 1], 100, 1), 'dist', 'binomial', 'link', 'logit');
mdl.SSE
ans = 23.9711
mdl.SSR
ans = 1.0278
mdl.SST
ans = 24.9900

You cannot use anova on a GLM, but only an LM. The link you provided is the same. I assume your response is continuous, so you can use fitlm. Also, it's easier if you share your data.
