I have a two dimensional array Array2, i’d like to be able of selecting rows use ndarray::{Array2, Axis}; let subarray: Array2 = my_array.select(Axis(0), &[0,2,5]); With that simple code i can select first, third and sixth row, but what about when the target indexes are built at run time, i mean i’d like to select from… Read More Rust ndarray: How can i select rows of an array from indexes

I was looking to update a row of 2D matrix in rust ndarray, but row_mut does not seem to allow me to update the row directly. For example (playground link) let mut array = array![[1., 2.], [3., 4.]]; let y = array![5., 5.]; array.row_mut(0) += &y; However it works if I assign the mutable slice… Read More Updating a row of a matrix in rust ndarray

I am trying to understand the "v" in ndarray (de)serialize: use ndarray::prelude::*; pub fn example() { let ar2 = arr2(&[[0., 0., 0., 0., 0.], [0., 0., 0., 0., 0.], [0., 0., 0., 0., 0.],[0., 0., 0., 0., 0.],[0., 0., 0., 0., 0.]]); let s = serde_json::to_string(&ar2).unwrap(); dbg!(s); let ar1 = arr1(&[[0., 0., 0., 0., 0.],… Read More What does "v" stand for in ndarray (de)serialize?
