Inplace column scaling of a CSR matrix.
Scale each feature of the data matrix by multiplying with specific scale provided by the caller assuming a (n_samples, n_features) shape.
- XCSR matrix with shape (n_samples, n_features)
Matrix to normalize using the variance of the features.
- scalefloat array with shape (n_features,)
Array of precomputed feature-wise values to use for scaling.
