Multiply a matrix by a vector matlab
WebMatrix multiplication is not universally commutative for nonscalar inputs. That is, A*B is typically not equal to B*A. If at least one input is scalar, then A*B is equivalent to A.*B and is commutative. C = mtimes (A,B) is an alternative way to execute A*B, but is rarely used. This MATLAB function multiplies arrays A and B by multiplying corresponding … An exception is when you take the dot product of a complex vector with itself. … Array vs. Matrix Operations Introduction.
