scipy.linalg.lapack.dgeequ

scipy.linalg.lapack.dgeequ(a) = <flapack function dgeequ>

Compute row and column scale factors that equilibrate a matrix (LAPACK dgeequ).

Parameters:

andarray

Matrix of shape (m, n).

Returns:

rndarray

Row scale factors, length m.

cndarray

Column scale factors, length n.

rowcndfloat

Ratio of the smallest to the largest row scale factor.

colcndfloat

Ratio of the smallest to the largest column scale factor.

amaxfloat

Largest element of a in absolute value.

infoint

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.
