# cupyx.scipy.sparse.linalg.norm¶

cupyx.scipy.sparse.linalg.norm(x, ord=None, axis=None)

Norm of a cupy.scipy.spmatrix

This function is able to return one of seven different sparse matrix norms, depending on the value of the ord parameter.

Parameters
• x (sparse matrix) – Input sparse matrix.

• ord (non-zero int, inf, -inf, 'fro', optional) – Order of the norm (see table under Notes). inf means numpy’s inf object.

• axis – (int, 2-tuple of ints, None, optional): If axis is an integer, it specifies the axis of x along which to compute the vector norms. If axis is a 2-tuple, it specifies the axes that hold 2-D matrices, and the matrix norms of these matrices are computed. If axis is None then either a vector norm (when x is 1-D) or a matrix norm (when x is 2-D) is returned.

Returns

0-D or 1-D array or norm(s).

Return type

ndarray
