Re: Maple's linear algebra routine and higher precision arithmetic

Hi, many thanks... I just want to test the validity of some lower
precision results with results generated by increasing levels of precision.

Would defining the matrix entries as -1.0 4.0 1.0 do the trick to force
floats?

Thanks,
R Haynes

Hi, does Maple's linear algebra routine MatrixInverse play nicely with the
Digits command? If I set Digits:=50 and compute a Matrix Inverse will the
arithmetic all be done to 50 digits?

Yes, it will (if the original matrix involves floats). Note that
"to 50 digits" doesn't mean that the results are accurate to 50 digits,
but rather that the calculations are done with Digits set to 50.
