Solve systems of linear equations Ax = B for x
Syntax and Description
A\B  solves the system of linear equations A*x = B. The matrices A and B must have the same number of rows. A warning message is displayed if A is badly scaled or nearly singular, but performs the calculation regardless.

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