scipy.linalg.svdvals

scipy.linalg.svdvals(a, overwrite_a=False)

Compute singular values of a matrix.

Parameters :

a : array, shape (M, N)

Matrix to decompose

overwrite_a : boolean

Whether data in a is overwritten (may improve performance)

Returns :

s: array, shape (K,) :

The singular values, sorted so that s[i] >= s[i+1]. K = min(M, N)

Raises LinAlgError if SVD computation does not converge :
