using 2 variables in one for loop

for i=5:8,a=1:4

for j=5:8,b=1:4

K(lm(i),lm(j))=Kg2(a,b);

end

end

Ks=Ks+K;

K=zeros(14);

How can I use this loop? As it is just picking values for i=1 and j=1 and not completing the loop.

for loop executes a group of statements in a loop for a specified number of times with a single index. In my understanding, you are trying to use 2 indexes. So a=1:4 and b=1:4 are being executed as statements. You can use the below code for your requirement

I=5:8;
A=1:4;
J =5:8;
B=1:4;
for p=1:numel(I)
    i=I(p);
    a=A(p);
    for q=1:numel(J)
        j=J(q);
        b=B(q);
        K(lm(i),lm(j))=Kg2(a,b);
    end
end
