WebJun 2, 2012 · MATLAB® has two different types of arithmetic operations: array operations and matrix operations. You can use these arithmetic operations to perform numeric computations, for example, adding two numbers, raising the elements of an array to a given power, or multiplying two matrices. Matrix operations follow the rules of linear algebra.

WebElement-by-Element multiplication of a and b. Both array must be the same shape, and one of them must be a scalar. Matrix Multiplication/td> a*b/td> Matrix multiplication of a and b. The number of column in a must equal the number of rows in b. Array Right Division/td> a ./ b/td> Element-by-element division of a and b: a (i, j) / b (i, j). 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. C = A.* B multiplies arrays A and B by multiplying corresponding elements. The … The result is a complex scalar since A and B are complex. In general, the dot product … Array vs. Matrix Operations Introduction. MATLAB ® has two different types of …

WebScalar multiplication is the process of multiplying every entry in a matrix by the same number; this number is called the "scalar". The word scalar comes from Latin, and has a sense of changing the scale of something.
