storing data from nested for loop

I'm having hard time to save RndmVarInput including IM, z50Final, Mat, and tYear, and scenario iteration number from the nested for loop below. tYear is 1by3 ; z50Final is 10by1; IM is 1by10; Mat is 10by3; would you please help me out how to save it in big matrrix or cell array.

Nrt=3;  
Nsnro=1000; 
lhsN=10; 
for scenario=1:Nsnro
    tYear=PoisProcs(Nrt);
    for i=1:Nrt
        z50Final=LHS_TimDepScour(lhsN,tYear);
        IM=LHS_seismic_hazard(lhsN);
        Mat = LHS_Materials(lhsN); 
        for j=1:lhsN
            SD = z50Final(j); 
            IM_PGA = IM(j);
            mat_var = Mat(j, :)'; 
        end
    end
end

You have to follow the similar approach as suggested earlier here:
