pub fn channel_stats(data: &Array2<f64>) -> Vec<(f64, f64, f64, f64)>Expand description
Compute (mean, max, min, std) for every channel in a (T, C) array.
NaN values are ignored in all statistics. Returns a vector of length C
where each entry is (mean, max, min, std). If a channel is entirely NaN
the tuple fields will be NaN.
