How can I get precise result?
显示 更早的评论
I'm new to Matlab and I did some test.
format longG
a = [1 -1 -1 3; 2 -1 -3 1; 3 2 -5 2; 3 1 2 2]
b = adjoint(a)
a * b
The result looks like this:
As you can see, there are a lot .9999999... and e-14 or e-15. These e-14 or e-15 numbers are actually all 0s. How can I get precise result?
I did a similar calculation in Mathematica, and below is the result.
How can I get this similar result in Matlab? Thanks.
