Two methods are given concerning the following problems of linear algebra over the field of complex numbers (or, less rigorously, linear problems with complex coefficients): the solving of a system of linear algebraic equations, the inversion of a matrix and the evaluation of a determinant. The second method is especially suitable for use with computers. In addition to the usual numerical checking, the second method also provides an effective form check.
