Re: matrix inversion in plan ?

This sort of thing would definitely compute the inverse. And it is definitely to be avoided. How about you give some specifics so I can say what should be done? On Sun, Oct 4, 2015 at 7:31 PM, go canal wrote: > Thank you all, the solver is something like this, am

Re: matrix inversion in plan ?

I will be more than interested to extend to complex double, when the solver is ready for double data type.  thanks, canal On Monday, October 5, 2015 2:02 PM, Ted Dunning wrote: On Sun, Oct 4, 2015 at 10:32 PM, go canal wrote: >

That isn't enough detail. How do you mean to compute degrees of freedom? WHy do you need the inverse to do this? Where did you get this algorithm? Is this even appropriate at large scale? Is this a stable computation? On Sun, Oct 4, 2015 at 11:18 PM, go canal
