`scipy.linalg._flapack:dgeequb`

Signature

def dgeequb(a)

Compute equilibration factors restricted to powers of the radix (LAPACK dgeequb).

r : ndarray: Row scale factors, length m.
c : ndarray: Column scale factors, length n.
rowcnd : float: Ratio of the smallest to the largest row scale factor.
colcnd : float: Ratio of the smallest to the largest column scale factor.
amax : float: Largest element of a in absolute value.
info : int: 0 on success; if negative, the -info-th argument had an illegal value; if 0 < info <= m, row info-1 is exactly zero; if info > m, column info-m-1 is exactly zero.
