interp
A Rust reimplementation of Matlab's interp1
function for linear interpolation.
API documentation is available on docs.rs.
Usage
Add interp
to your Cargo.toml
file:
[dependencies]
interp = "1.0"
Or, if you need the interp_array
feature (only supported on Rust 1.55.0 or later)
[dependencies]
interp = { version = "1.0", features = ["interp_array"] }
Example
use interp::interp;
let x = vec![0.0, 0.2, 0.5, 0.8, 1.0];
let y = vec![0.0, 1.0, 3.0, 3.5, 4.0];
// Interpolate at a single point
assert_eq!(interp(&x, &y, 0.35), 2.0);
// Interpolate a vec
let xp = vec![0.1, 0.65, 0.9];
assert_eq!(interp_slice(&x, &y, &xp), vec![0.5, 3.25, 3.75]);
// Interpolate an array (requires the interp_array feature and Rust 1.55.0+)
let xp = [0.1, 0.65, 0.9];
assert_eq!(interp_array(&x, &y, &xp), [0.5, 3.25, 3.75]);
Full API documentation is available on docs.rs.
