From https://netlib.org/lapack/explore-html-3.6.1/d6/dee/zheev_8f_a70c041fd19635ff621cfd5d804bd7a30.html,

Zheev is for double precision, as double precision, dimension( * ) W,

I searched a bit. From https://people.math.sc.edu/Burkardt/f_src/linpack_q/linpack_q.html
the List of Routines: does not have zheev.

Is there any quadruple precision zheev in Fortran? If not, is there any similar in Python?
