WebStep 1: First, check if it's a square matrix, as only square matrices can be considered as symmetric matrices. Step 2: Find the transpose of the given matrix. Step 3: If the transpose of the matrix is equal to the matrix itself, then it is a symmetric matrix. Explore WebThe zero matrix, denoted by 0, can be any size and is a matrix consisting of all zero elements. Multiplication by a zero matrix results in a zero matrix. The identity matrix, denoted by I, is a square matrix (number of rows equals number of columns) with ones down the main diagonal.

WebJun 15, 2024 · Matrix multiplication has the following properties: 1. Associativity: A(BC) = (AB)C. 2. Left distributivity: A(B+C) = AB+AC. 3. Right distributivity: (A+B)C = AC+BC. 4. IA = A = AI. 5. α(BC) = (αB)C = B(αC). (α is a scalar; A, B & C are matrices, I is the identity matrix. A,B,C & I are of orders m×n, n×p, p×r & m×m respectively.) WebThe three important properties of determinants are as follows.. Property 1:The rows or columns of a determinant can be swapped without a change in the value of the determinant.
