mathematica

[nbo10]

Hi All,
I'm using mathematica to solve a few NxN matrices, but the eigen(values/vectors) comes back with 0. i, which is zero but how do I evaluate it as zero so that I can do comparison, > < =, etc... Thanks

I don't know exactly how to do it in mathematica, but I think you could filter out the real component and compare that.
