WebJan 14, 2012 · Mathematica returns normalized eigenvectors for numeric matrices. p2 = Transpose[Eigenvectors[N[a]]] This is risky, though, because computing the inverse of a numeric matrix can often fail spectacularly due to various numerical errors. WebIt invokes as many separate Mathematica evaluations as the length of the diagonal. It will unpack packed Real arrays when written like this because it assigns 0 instead of 0.0 . A better solution would explicitly need to check for packed arrays, detect their type (integer or real/complex) and assign the appropriate element.
