# cupy.linalg.svd¶

cupy.linalg.svd(a, full_matrices=True, compute_uv=True)[source]

Singular Value Decomposition.

Factorizes the matrix a as u * np.diag(s) * v, where u and v are unitary and s is an one-dimensional array of a’s singular values.

Parameters: a (cupy.ndarray) – The input matrix with dimension (M, N). full_matrices (bool) – If True, it returns u and v with dimensions (M, M) and (N, N). Otherwise, the dimensions of u and v are respectively (M, K) and (K, N), where K = min(M, N). compute_uv (bool) – If False, it only returns singular values. A tuple of (u, s, v) such that a = u * np.diag(s) * v. tuple of cupy.ndarray

Warning

This function calls one or more cuSOLVER routine(s) which may yield invalid results if input conditions are not met. To detect these invalid results, you can set the linalg configuration to a value that is not ignore in cupyx.errstate() or cupyx.seterr().
