scipy.linalg.lapack.dgerqf

scipy.linalg.lapack.dgerqf = <fortran object>

dgerqf - Function signature:

qr,tau,work,info = dgerqf(a,[lwork,overwrite_a])

Required arguments:

a : input rank-2 array(‘d’) with bounds (m,n)

Optional arguments:

overwrite_a := 0 input int lwork := 3*m input int

Return objects:

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
