# scipy.linalg.lapack.zhbevx

`scipy.linalg.lapack.``zhbevx` = <fortran object>
  zhbevx - Function signature:
    w,z,m,ifail,info = zhbevx(ab,vl,vu,il,iu,[ldab,compute_v,range,lower,abstol,mmax,overwrite_ab])
  Required arguments:
    ab : input rank-2 array(‘D’) with bounds (ldab,*) vl : input float vu : input float il : input int iu : input int
  Optional arguments:
    overwrite_ab := 1 input int ldab := shape(ab,0) input int compute_v := 1 input int range := 0 input int lower := 0 input int abstol := 0.0 input float mmax := (compute_v?(range==2?(iu-il+1):n):1) input int
  Return objects:
    w : rank-1 array(‘d’) with bounds (n) z : rank-2 array(‘D’) with bounds (ldz,mmax) m : int ifail : rank-1 array(‘i’) with bounds ((compute_v?n:1)) info : int
