qr : rank-2 array(‘d’) with bounds (m,n) and a storage
jpvt : rank-1 array(‘i’) with bounds (n)
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: max(3*(n+1),1)
