The divide operator / is really a combination of three operators, all of which have the same general syntax: 
Y = A / B
 where A and B are arrays of numerical type. The result Y depends on which of the following three situations applies to the arguments A and B: 
A is a scalar, B is an arbitrary n-dimensional numerical array, in which case the output is the scalar A divided into each element of B.  B is a scalar, A is an arbitrary n-dimensional numerical array, in which case the output is each element of A divided by the scalar B.  A,B are matrices with the same number of columns, i.e., A is of size K x M, and B is of size L x M, in which case the output is of size K x L.  The output follows the standard type promotion rules, although in the first two cases, if A and B are integers, the output is an integer also, while in the third case if A and B are integers, the output is of type double.
There are three formulae for the times operator. For the first form
![\[ Y(m_1,\ldots,m_d) = \frac{A}{B(m_1,\ldots,m_d)}, \]](form_132.png) 
and the second form
![\[ Y(m_1,\ldots,m_d) = \frac{A(m_1,\ldots,m_d)}{B}. \]](form_133.png) 
In the third form, the output is defined as:
![\[ Y = (B' \backslash A')' \]](form_134.png) 
 and is used in the equation Y B = A. 
The right-divide operator is much less frequently used than the left-divide operator, but the concepts are similar. It can be used to find least-squares and minimum norm solutions. It can also be used to solve systems of equations in much the same way. Here's a simple example:
--> B = [1,1;0,1]; --> A = [4,5] A = 4 5 --> A/B ans = 4 1
