What is the determinant of a matrix times a scalar?
WebScalar Matrix. A scalar matrix is a type of diagonal matrix. The diagonal elements of the scalar matrix are equal or same. If the elements of the scalar matrix are all equal to 1, then it becomes an identity matrix. A square matrix A = [a ij] n x n, is said to be a scalar matrix if; a ij = 0, when i ≠ j. a ij = k, when i = j, for some constant k.
