fplot.m: Overhaul function for Matlab compatibility and performance (bug #38961). * scripts/plot/fplot.m: Add ability to specify n,tol,fmt in any order and simultaneously. Return data rather than plotting it if asked. Use additional test on progress of algorithm to decide whether to quit. Add %!demo and %!tests.
