Solve systems of linear equations xA = B for x
Syntax and Description
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. A warning message is displayed if A is badly scaled or nearly singular, but performs the calculation regardless.

mrdivide(B,A)  is an alternative way to execute x = B/A, but is rarely used.
