ferray-ma

Masked arrays with mask propagation for the ferray scientific computing library.

What's in this crate

• MaskedArray<T, D> — array with boolean mask for missing/invalid data
• Mask propagation: arithmetic and ufuncs automatically propagate masks
• Masked reductions: masked_mean, masked_sum, masked_var, masked_std, etc.
• Masked sorting: operations that respect the mask

Implements numpy.ma for Rust.

Usage

use ferray_ma::MaskedArray;
use ferray_core::prelude::*;

let data = Array1::<f64>::from_vec(Ix1::new([4]), vec![1.0, 2.0, 3.0, 4.0])?;
let mask = vec![false, false, true, false]; // mask out index 2
let ma = MaskedArray::new(data, mask)?;

This crate is re-exported through the main ferray crate with the ma feature (enabled by default).
