Matrix negative fraction power
Dear list,
I understand that to raise matrix A to power (-1/2) we should use something
like this:
eigen(A)$vectors%*%diag(1/sqrt(eigen(A)$values))%*%t(eigen(A)$vectors)
[from previous discussions:
http://r.789695.n4.nabble.com/matrix-power-td900335.html]
But this will only do it for negative sqrt of the matrix not for other
fraction powers like (-3/2).
Seeing that these things be can done seamlessly in Matlab, I am wondering
if I am missing something in R.
Examples in Matlab:
A =
1 1 1
1 2 3
1 3 6
A...
