I've been using
NSolve a moderate (50-100 equations) size system of linear equations and it has been working splendidly (
Solve on the other hand is extremely slow) and I thought I'd look up the method it is using is there anyway to:
a) See which method Mathematica chooses to use for a particular set of equations?
b) See what are the available methods to NSolve. The documentation for
NSolve doesn't show anything specific under Details and Options.
