Matrix Operations

Matrices are rectangular arrays of numbers arranged in rows and columns. They are powerful mathematical tools used in linear algebra, computer graphics, physics, and many other fields.

Matrix Addition and Subtraction

To add or subtract matrices, both matrices must have the same dimensions. The result is a matrix where each element is the sum or difference of the corresponding elements in the two matrices.

Matrix Multiplication

For matrix multiplication (A × B), the number of columns in matrix A must equal the number of rows in matrix B. If A is an m × n matrix and B is an n × p matrix, then the product AB is an m × p matrix.

Determinant

The determinant is a scalar value calculated from a square matrix. It provides information about the matrix such as whether it is invertible. A matrix is invertible if and only if its determinant is not zero.

Matrix Inverse

The inverse of a square matrix A is another matrix A⁻¹ such that A × A⁻¹ = A⁻¹ × A = I, where I is the identity matrix. A matrix has an inverse if and only if its determinant is not zero.

Matrix Transpose

The transpose of a matrix is obtained by flipping the matrix over its diagonal, switching the row and column indices. If A is an m × n matrix, then Aᵀ is an n × m matrix.
