[Lapack] Matrix inversion

Dear Dr Kale,
Look at DSYTRI (symmetric indefinite matrix)  or DPOTRI (symmetric positive 
definite matrix) depending on your need.

Hi lapack team,

I am looking for a fast reliable Fortran subroutine to 
invert a symmetric matrix using double precision 
arithmetic.  I took a look at the list of functions on 
your website, but could not find one that did that 
directly.  Where can I find it?

Thank you for your help,
