Trait for 2D-array

Provided Methods§

Source

fn max(&self, axis: u8) -> Vec<T>
where T: Number + PartialOrd,

return max value in array

Source

fn sum(&self, axis: u8) -> Vec<T>
where T: Number,

return sum of element of array

Source

fn min(&self, axis: u8) -> Vec<T>
where T: Number + PartialOrd,

return min value of array

Source

fn argmax(&self, axis: u8) -> Vec<usize>
where T: Number + PartialOrd,

return positions of max values in both rows

Source

fn mean_by(&self, axis: u8) -> Vec<f64>

Source

fn display(&self, f: &mut Formatter<'_>) -> Result

print out array

Source

fn norm(&self, p: f64) -> f64
where T: Number,
