# scipy.linalg.lapack.zungrq

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

  Wrapper for `zungrq`.

  Parameters: | a : input rank-2 array(‘D’) with bounds (m,n) tau : input rank-1 array(‘D’) with bounds (k)
  Returns: | q : rank-2 array(‘D’) with bounds (m,n) and a storage 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
