# scipy.linalg.lapack.zgbtrf

`scipy.linalg.lapack.``zgbtrf`(ab, kl, ku[, m, n, ldab, overwrite_ab]) = <fortran object>

  Wrapper for `zgbtrf`.

  Parameters: | ab : input rank-2 array(‘D’) with bounds (ldab,*) kl : input int ku : input int
  Returns: | lu : rank-2 array(‘D’) with bounds (ldab,*) and ab storage ipiv : rank-1 array(‘i’) with bounds (MIN(m,n)) info : int
  Other Parameters:

  m : input int, optional

  > Default: shape(ab,1)

  n : input int, optional

  > Default: shape(ab,1)

  overwrite_ab : input int, optional

  > Default: 0

  ldab : input int, optional

  > Default: shape(ab,0)
