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

Wrapper for sgeqrf.

Parameters:

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

Returns:

qr : rank-2 array(‘f’) with bounds (m,n) and a storage

tau : rank-1 array(‘f’) with bounds (MIN(m,n))

work : rank-1 array(‘f’) 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)
