It only works fine when using "approx([V]/[P])" but not for simply doing "[V]/[P]", which would be the most obvious way when working in Home environment ... Why that??

So what is the reason why the "powerful" Prime shouldn't be able to do this matrix inversion in a correct way in numerical mode too?? Perhaps somebody involved in the Prime development can further explain why the 50g succeeds and the Prime fails? What is the difference? (07152015 08:28 PM)Anders Wrote: ...+1
