I have a for loop which is the following
for i=1:2
bm(i) = bm + yi(i)*b1(i);
for j=1:2
aam(i,j)=aam+yi(i)*yi(j)*sqrt(aa(i)*aa(j));
end
end
for the yi and aa I have two values for each that I need to be multiplied to each other in each loop, and I'm not sure how exactly to do it.

No loop needed. Assumed yi and aa row vectors.
bm=bm+yi.*b1;
aam = aam+(yi'.*yi).*sqrt(aa'.*aa);

if you want to use 'loop'
b1=5; % assuming value
yi=[2,3]; % assuming value
aa=[4,4]; % assuming value
bm=3; % assuming value
aam=4; % assuming value
C=cell(1,2);
for i=1
for j=2
C{1,i} = bm + yi(i)*b1;
C{1,j}=aam+yi(i)*yi(j)*sqrt(aa(i)*aa(j));
end
end
Output=[C{:}];
