[Insight-users] how to calculate the sqrt of a matrix

[Luis Ibanez]

Hi Achille,

You should have mention from the beginning that your matrix
was diagonal.

In that case you simply need to compute the square root
of each one of the diagonal elements.

There is no need for you to use the Cholesky decomposition.


    Regards,


       Luis
