`scipy.linalg.lapack.``dgerqf`(a[, lwork, overwrite_a]) = <fortran object>

  Wrapper for `dgerqf`.

  Parameters: | a : input rank-2 array(‘d’) with bounds (m,n)
  Returns: | qr : rank-2 array(‘d’) with bounds (m,n) and a storage tau : rank-1 array(‘d’) with bounds (MIN(m,n)) work : rank-1 array(‘d’) with bounds (MAX(lwork,1)) info : int
  Other Parameters:

  overwrite_a : input int, optional

  > Default: 0

  lwork : input int, optional

  > Default: 3*m
