# scipy.linalg.lapack.dgges

`scipy.linalg.lapack.``dgges`(dselect, a, b[, jobvsl, jobvsr, sort_t, ldvsl, ldvsr, lwork, dselect_extra_args, overwrite_a, overwrite_b]) = <fortran object>

  Wrapper for `dgges`.

  Parameters: | dselect : call-back function a : input rank-2 array(‘d’) with bounds (lda,*) b : input rank-2 array(‘d’) with bounds (ldb,*)
  Returns: | a : rank-2 array(‘d’) with bounds (lda,*) b : rank-2 array(‘d’) with bounds (ldb,*) sdim : int alphar : rank-1 array(‘d’) with bounds (n) alphai : rank-1 array(‘d’) with bounds (n) beta : rank-1 array(‘d’) with bounds (n) vsl : rank-2 array(‘d’) with bounds (ldvsl,n) vsr : rank-2 array(‘d’) with bounds (ldvsr,n) work : rank-1 array(‘d’) with bounds (MAX(lwork,1)) info : int
  Other Parameters:
  | jobvsl : input int, optional Default: 1 jobvsr : input int, optional Default: 1 sort_t : input int, optional Default: 0 dselect_extra_args : input tuple, optional Default: () overwrite_a : input int, optional Default: 0 overwrite_b : input int, optional Default: 0 ldvsl : input int, optional Default: ((jobvsl==1)?n:1) ldvsr : input int, optional Default: ((jobvsr==1)?n:1) lwork : input int, optional Default: 8*n+16

  Notes

      Required arguments:
        alphar : input float
        alphai : input float
        beta : input float
      Return objects:
        dselect : int
