Vector addition with 2-dim array

A is an R by C (R x C) array and I have a rows vector V with length C. I want to add or subtract V from every rows in the array A.

Is there any way to simplify this procedure?

Of course I know some method like:

VV = V(onese(1:R), :)
result = A +/- VV;

but I just wanted an one-line command or operator, like:

result = A ※ V
result = somefunction(A, V);

I need to find ※ or somefunction()

ones(1:R) creates a matrix with R dimensions and prod(1:R) elements. You mean ones(1, R).

The one-line command might have the advantage, that the matrix VV is not created explicitly:

result = A - v(ones(R,1), :);

you could use this oneliner:

 result = A - (ones(size(A,1),1)*v);

[Wouter]

and if v is a column vector you need to transpose v:

 result = A - (ones(size(A,1),1)*v');

A = rand(3,4);
b = rand(1,4);
C = bsxfun(@minus, A, b);
