Webvectors, however, the more general matrix case is not considered. In [13], they ﬁnd derivatives of scalar functions with respect to complex-valued matrices, however, that paper could have been simpliﬁed a lot if the proposed theory was utilized. Examples of problems where the unknown matrix is a complex-valued matrix are wide ranging WebIn the case of the metric, this implies that − det ( g + δ g) ≈ − det ( g) [ 1 + g a b δ g a b] and so δ ( − g) = ( − g) g a b δ g a b. To complete the calculation you'll then have to relate δ g a b to δ g a b, but this should get you on your way. If this isn't a homework problem or the like, let me know and I can expand on this latter part. Share opac pontcharra
