Matrix left division. A\B solves the symbolic linear equations A*X=B for X. Note that A\B is roughly equivalent to inv(A)*B. Warning messages are produced if X does not exist or is not unique. Rectangular matrices A are allowed, but the equations must be consistent; a least squares solution is not computed.
.\
Array left division. A.\B is the matrix with entries B(i,j)/A(i,j). A and B must have the same dimensions, unless one is scalar.

Matrix right division. B/A solves the symbolic linear equation X*A=B for X. Note that B/A is the same as (A.'\B.').'. Warning messages are produced if X does not exist or is not unique. Rectangular matrices A are allowed, but the equations must be consistent; a least squares solution is not computed.
