how to add multidimensional arrays

Hi all,

I have the following commands:

 j=1:N
 elem(j,1,1)=alfa(j).*E0(1,1).*sigma(j,1,1);
 elem(j,1,2)=alfa(j).*E0(1,2).*sigma(j,1,2);
 elem(j,2,1)=alfa(j).*E0(2,1).*sigma(j,2,1);
 elem(j,2,2)=alfa(j).*E0(2,2).*sigma(j,2,2);

Is there a way to write them in one compact form rather than four lines? Thank you.

I think this will do what you want.

elem(j,1:2,1:2) = alfa(j).*E0(1:2,1:2).*sigma(1:2,1:2);

If each of those dimensions only runs over 1:2, then this can be shortened to

elem(j,:,:) = alfa(j).*E0.*sigma(j,:,:);
