x = B/A solves
the system of linear equations x*A = B for x.
The matrices A and B must
contain the same number of columns. MATLAB^{®} displays
a warning message if A is badly scaled or nearly
singular, but performs the calculation regardless.

If A is a scalar, then B/A is
equivalent to B./A.

If A is a square n-by-n matrix
and B is a matrix with n columns,
then x = B/A is a solution to the equation x*A
= B, if it exists.

If A is a rectangular m-by-n matrix
with m ~= n, and B is a matrix
with n columns, then x=B/A returns
a least-squares solution of the system of equations x*A =
B.

x = mrdivide(B,A) is
an alternative way to execute x=B/A,
but is rarely used. It enables operator overloading for classes.
