Matrix multiplication and trace can any body help me

Hi,

I have a A(5X5) matrix and a B(5X5X10) matrix. I want to compute Trace(A*B(:,:,1))+Trace(A*B(:,:,2)) +…+Trace(A*B(:,:,10))

Any direct/efficient way of doing this without the for loop?

Thank you very much,

result=sum( A.'.*sum(B,3) ,'all')
