# scipy.linalg.lapack.dgges

`scipy.linalg.lapack.``dgges` = <fortran object>
  dgges - Function signature:
    a,b,sdim,alphar,alphai,beta,vsl,vsr,work,info = dgges(dselect,a,b,[jobvsl,jobvsr,sort_t,ldvsl,ldvsr,lwork,dselect_extra_args,overwrite_a,overwrite_b])
  Required arguments:
    dselect : call-back function a : input rank-2 array(‘d’) with bounds (lda,*) b : input rank-2 array(‘d’) with bounds (ldb,*)
  Optional arguments:
    jobvsl := 1 input int jobvsr := 1 input int sort_t := 0 input int dselect_extra_args := () input tuple overwrite_a := 0 input int overwrite_b := 0 input int ldvsl := ((jobvsl==1)?n:1) input int ldvsr := ((jobvsr==1)?n:1) input int lwork := 8*n+16 input int
  Return objects:
    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
  Call-back functions:

    def dselect(alphar,alphai,beta): return dselect Required arguments:

    > alphar : input float alphai : input float beta : input float

    Return objects:
      dselect : int
