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:

toml [dependencies] interp = "1.0"

Or, if you need the interp_array feature (only supported on Rust 1.55.0 or later)

toml [dependencies] interp = { version = "1.0", features = ["interp_array"] }

Example

```rust 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]; asserteq!(interpslice(&x, &y, &xp), vec![0.5, 3.25, 3.75]);

// Interpolate an array (requires the interparray feature and Rust 1.55.0+) let xp = [0.1, 0.65, 0.9]; asserteq!(interp_array(&x, &y, &xp), [0.5, 3.25, 3.75]); ```

Full API documentation is available on docs.rs.
