sklearn.utils.sparsefuncs.inplace_row_scale¶
- 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.
