how to add matrix ?

Question

Aniket 2013-5-13

I have Aik = 2*2 matrix and i want to add another matrix of 2*2 to Aik matrix ...

for example

 w = [100 200]; % frequency vector
 m = length(w);
 Aik = zeros(2,2,m); % matrix for 2 frequencies
 for i = 1:m
   Aik(:,:,i) = [0 1; w(i) 0];

end

the above code create Aik matrix of 2*2 for each frequency mentioned in the frequency vector 'w'.

but now i want to add another 2*2 matrix

for example

b = [0 1;0 0]

this b matrix I want to add with Aik for both dimensions

Aik(: ,: , 1)+ b and Aik(: ,: , 2)+ b

how should i do this in the loop ?
