two vectors subtraction works but division returning single number and not vector

In MATLAB I have two vectors which are both 1 x 310 of type doubles.

So I have a line shown below. ret & bret are my vectors. This result produces another vector act_r of 1 X 310 of type double - all makes sense.

act_r = (ret - bret);

However when I try to divide every element in ret by its corresponding element in bret (again shown below) I get a single number. Why is this? How do I get Matlab to divide every element in ret by the corresponding element in bret?

act_d = (ret / bret);

MATLAB (the name comes from MATrix LABoratory) per default excutes matrix operation so ret/bret will be evaluated as a matrix operation: 

x = B/A

uses the mrdivide operator (a overload of / ) which solves systems of linear equations xA = B for x hence returning a scalar.

while x =A./B uses the rdivide operator which divides each element of A by the corresponding element of B
