f1=zeros(1,100);
f2=zeros(1,100);
f3=zeros(1,200);
c1=randi([1,20],1,100);
c2=randi([1,20],1,100);
y(1,1:200)=rand(1,200);
f1(1,1:100)=[y(1,1:100).*c1];
f2(1,1:100)=[y(1,101:200).*c2];
f3(1,1:200)=horzcat(f1,f2);
g1=zeros(1,100);
g2=zeros(1,100);
g1=gradient(f1,y(1:100));
g2=gradient(f2,y(101:200));
g=horzcat(g1,g2);
my question is whether g1 and g2 are sub-gradients of f1 and f2 respectively in the above code

No. Lagrangian sub-gradient methods apply to functions, but you do not have functions.
gradient() applied to numeric matrices is numeric differences, and the second and following arguments give the step sizes.
