Hi,
I am creating a GUI and need to use data from m.file. It's working for the first file, but not or the second. Both are (double). Any idea?
matrice_losses.mat is load, but not MM...
Regards

It is possible that you can load matrice_losses because you subsequently "do something" to it, either inside your function or elsewhere in the code. That means it is a nested variable within your GUI workspace (I dont know the correct terms, sorry ;)
MM, however, is just loaded and done nothing with. Try initializing MM outside the function, or calling it from another function in the GUI.
I'm just spitballing here. If one thing can load, another should be able to, and this is the only difference I can see out of what you posted.

Bad code practices strike again!
You can easily avoid this error by loading into an output variable (which you should be doing anyway), e.g.:
S = load('matrice_losses.mat');
lamfit = S.matrice_losses(:,1).*1e-3;
lossdB = S.matrice_losses(:,2);

function PushB(hObject,eventdata,handles)
load matrice_losses
lamfit=(matrice_losses(:,1).*1e-3)
lossdB =matrice_losses(:,2);
u=load('MM.mat')
mm=u.mm
end
