Welcome to the guide on matrix operations! Matrices are a fundamental concept in linear algebra and have a wide range of applications in various fields such as physics, engineering, computer science, and more. In this section, we will explore the basic operations that can be performed on matrices.

Basic Matrix Operations

Addition and Subtraction

Matrix addition and subtraction are straightforward operations. Two matrices can be added or subtracted if they have the same dimensions. The resulting matrix will have the same dimensions as the original matrices.

  • Addition: To add two matrices, simply add the corresponding elements from each matrix.

  • Subtraction: Similarly, to subtract two matrices, subtract the corresponding elements from each matrix.

Multiplication

Matrix multiplication is a more complex operation and requires that the number of columns in the first matrix be equal to the number of rows in the second matrix. The resulting matrix will have the same number of rows as the first matrix and the same number of columns as the second matrix.

  • Multiplication: To multiply two matrices, multiply the corresponding elements from each row of the first matrix with the corresponding elements from each column of the second matrix and sum the products.
