sklearn.utils.sparsefuncs.inplace_row_scale(X, scale) [source]

Inplace row scaling of a CSR or CSC matrix.

Scale each row of the data matrix by multiplying with specific scale provided by the caller assuming a (n_samples, n_features) shape.

Parameters:	X : CSR or CSC sparse matrix, shape (n_samples, n_features) Matrix to be scaled. scale : float array with shape (n_features,) Array of precomputed sample-wise values to use for scaling.
