A diagonal matrix is a square matrix where every element except the leading diagonal is zero.
Since most of the elements are zero, certain calculations on the matrix are a lot easier than a general matrix. For example, the determinant of a large, general matrix involves a large number of multiplications, but the determinant of a diagonal matrix is simply the product of the diagonal elements.
