[Vxl-users] complex squareroot?

[Martin R. <mr...@gm...>]

Hi,

is there a way to compute a squareroot of a complex number in vnl?

Actually what I am trying to achieve is to use vnl_complex_eigensystem
on a real matrix to compute eigenvectors and complex eigenvalues, then
compute the squareroot of the eigenvalues and finally the squareroot of
the original matrix. Of course it would be nice to have a sqrtm
functions (see matlab) to do all this for me.


Thanks for any hints, Martin
