Mathematically, we express multiplication of a matrix A by a scalar as . where c is the scalar. Thus, multiplication by the scalar 3 is accomplished as: Multiplication of Matrices . Multiplication of one matrix by another is more complicated than scalar multiplication, and is carried out in accordance with a …

That is, the addition or subtraction operator is applied element-by-element, and the result is a third matrix whose dimensions are identical with those of the original matrices. Other element-wise operators employed by Matlab include: Scalar multiplication: Matrix exponentiation: Trigonometric functions of a matrix, e.g.: Logarithm of a matrix:

32 Notice that MATLAB does not distinguish between a 1x1 matrix (which is what vTw really is) and its single entry. Neither do we ordinarily, but we should remember that the product of a scalar with a matrix is not in general an instance of matrix multiplication. Notice also that the dot product is symmetric as regards v and w.

They are called scalar multiplication and matrix multiplication. Scalar Multiplication: If “k” is any non-zero scalar (constant) and if A is any matrix with entries aij and . dim [A] = p(n, then there exists a matrix B = kA with dim [B] = dim [A] = p(n, and entries. bij = kaij. The matrix B is called the scalar multiple of A by k.

This section demonstrates how to use MATLAB as a calculator. MATLAB is designed to work on matrices. However, if we treat a scalar as a 1x1 matrix, MATLAB resembles a calculator. Table 2 shows the basic math operators. Table 3 lists elementary math functions. The rules of precedence are given below: 1. Expressions are evaluated from left to ...
