Operations with Matrices As far as linear algebra is concerned, the two most important operations with vectors are vector addition [adding two (or more) vectors] and scalar multiplication (multiplying a vectro by a scalar). Analogous operations are defined for matrices Because the entries are numbers, we can perform operations on matrices. We add or subtract matrices by adding or subtracting corresponding entries. In order to do this, the entries must correspond. Therefore, addition and subtraction of matrices is only possible when the matrices have the same dimensions. We can add or subtract a [latex]\text{ }3\text{ }\times \text{ }3\text{ }[/latex] matrix and another [latex]\text{ }3\text{ }\times \text{ }3\text{ }[/latex] matrix, but we cannot add or. * In this article, we will discuss various operations on matrices and their properties: Matrices Addition - The addition of two matrices A m*n and B m*n gives a matrix C m*n*. The elements of C are sum of corresponding elements in A and B which can be shown as: The algorithm for addition of matrices can be written as

TheThe ORDERORDER of a matrixof a matrix is the number of theis the number of the rows and columns.rows and columns A matrix is an array of numbers arranged in the form of rows and columns. The number of rows and columns of a matrix are known as its dimensions which is given by m \(\times\) n, where m and n represent the number of rows and columns respectively. Apart from basic mathematical operations there are certain elementary operations that can be performed on matrix namely transformations Addition of matrices To define the addition of two matrices A = [ a i j] and B = [ b i j], they must have equal dimensions. The result of addition of these two matrices is matrix C = [ c i j] which has the same dimensions and a i j + b i j = c i j, ∀ i = 1, , m, ∀ j = 1, ,

If A and B are two matrices of the same order, then they are said to be conformable for subtraction. The difference of the matrix B from A is denoted by A-B and it is obtained by subtracting the elements of B from the corresponding elements of A. The order of the matrix A-B is same as the order of A or B Because the entries are numbers, we can perform operations on matrices. We add or subtract matrices by adding or subtracting corresponding entries. In order to do this, the entries must correspond. Therefore, addition and subtraction of matrices is only possible when the matrices have the same dimensions If A and B are square matrices such that. AB = I and BA = I then B is (A) Unit matrix (B) Null matrix (C) Multiplicative inverse matrix of A (D) -A. Solution.

Matrix Representation. The symmetry operations in a group may be represented by a set of transformation matrices \(\Gamma\)\((g)\), one for each symmetry element \(g\).Each individual matrix is called a represen tative of the corresponding symmetry operation, and the complete set of matrices is called a matrix representati on of the group. The matrix representatives act on some chosen basis. ** The main idea is that matrices hide linear equations, and the way in which they hide them is dependent on the laws of matrix multiplication**. It's linear with respect to row operations, because that's the same as redundant operations. But it's not the same with respect to column operations Operating on Matrices.
