Hi, I want to answer of 2 arrays without using loops,
A=rand(100,100)
B=rand(8,1)
The out put C is going to be a 100*100*8 array, each layer is the difference between A and corresponding B row.
e.g. The second layer of C is gonna be A(:,:)-B(2,:).
Is there a way to manage this with out for loop?
Thanks

For MATLAB versions R2016b+:
C = A - reshape(B,1,1,[])
For earlier versions:
C = bsxfun(@minus,A,reshape(B,1,1,[]))
