Polar decomposition is a fundamental tool in the theory of finitedimensional Lie groups and Lie algebras. For this reason, it is intimately related to the exponential map. We shall not consider these two notions here in their full generality, but we shall restrict attention to their matricial ...
Methods involving approximation theory, differential equations, the matrix eigenvalues, and the matrix characteristic polynomial have been proposed. In practice, consideration of computational stability and efficiency indicates that some of the methods are preferable to others, but that none are completely ...

THE EXPONENTIAL OF A MATRIX 5 The accuracy of an algorithm refers primarily to the error introduced by truncating in?nite series or terminating iterations. It is one component, but not the only component, of the accuracy of the computed answer. Often, using more computer time will increase ...

When continuing the solution of the matrix exponential function to SU(4), the four real roots of a quartic polynomial are determined with the help of a cubic resolvent equation that also belongs to the irreducible case. As an interesting byproduct of this analysis one obtains the shape of ...
