Scalar Multiplication of Matrices
For any matrix A = [aij]m×n if we multiply the matrix A with any scaler (say k) then the scaler is multiplied by each element of the matrix and this is called the scalar multiplication of matrices.
For any matrix A = if it is multiplied by any scaler k then,
kA =
Properties of Scalar Multiplication
For any matrices, A and B of the same order and λ and μ are any two scalars, then,
- λ(A + B) = λA + λB
- (λ + μ)A = λA + μA
- λ(μA) = (λμA) = μ(λA)
- (-λA) = -(λA) = λ(-A)
Matrix Operations
Matrix Operations are the operations that are operated on the matrix. Matrix Operation includes operations such as Addition of Matrix, Subtraction of Matrix, Multiplication of Matrix, etc, and others. These operations are very b useful for solving various problems of matrices and help us to find the transpose, inverse, rank, and others of the matrix. These operations help us to combine two or matrices.
In this article, we will learn about, Matrix Operations, Examples, and others in detail.
