# scipy.linalg.lapack.dsbevx

`scipy.linalg.lapack.``dsbevx`(ab, vl, vu, il, iu[, ldab, compute_v, range, lower, abstol, mmax, overwrite_ab]) = <fortran object>

  Wrapper for `dsbevx`.

  Parameters: | ab : input rank-2 array(‘d’) with bounds (ldab,*) vl : input float vu : input float il : input int iu : input int
  Returns: | 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
  Other Parameters:

  overwrite_ab : input int, optional

  > Default: 1

  ldab : input int, optional

  > Default: shape(ab,0)

  compute_v : input int, optional

  > Default: 1

  range : input int, optional

  > Default: 0

  lower : input int, optional

  > Default: 0

  abstol : input float, optional

  > Default: 0.0

  mmax : input int, optional

  > Default: (compute_v?(range==2?(iu-il+1):n):1)
