WebA square matrix is a matrix in which the number of rows = the number of columns. For example, matrices of orders 2x2, 3x3, 4x4, etc are square matrices. Matrices of orders like 2x3, 3x2, 4x5, etc are NOT square matrices (these are rectangular matrices ). WebThe determinant of any square matrix A is a scalar, denoted det(A).
