Function normalize 

pub fn normalize(
    x: &Array2<Float>,
    norm: NormType,
    axis: usize,
) -> Result<Array2<Float>>

Scale samples individually to unit norm

Each sample (i.e. each row of the data matrix) with at least one non-zero component is rescaled independently of other samples so that its norm equals one.

Arguments

• x - The data to normalize
• norm - The norm to use (‘l1’, ‘l2’, or ‘max’)
• axis - Axis along which to normalize (1 for samples, 0 for features)

Returns

Normalized data
