 Square matrix

A matrix with the same number of rows and columns represents an endomorphism of a finite-dimensional vector space after choosing a basis. Square matrices support trace, determinant, powers and the matrix exponential.

A **square matrix** is a type of matrix in which the number of rows is equal to the number of columns. In other words, a square matrix has the same dimension in both its rows and columns. For example, a 2x2 matrix or a 3x3 matrix is considered a square matrix.
