I've used 'symbolic' calculation in mathematica in many ways, but this time, I wonder if mathematica can solve symbolic matrix operation. Specifically, m = {{a, b}, {c, d}, {e, f}} SingluarValues[m] returns SingularValues::"svdf": "SingularValues has received a matrix with infinite precision." (a,b,c,d,e,f are all symbolics.) I need to do several symbolic matrix operations such as SingularValues. Is there any way to do that? Thank you.
