hann_window

hann_window(
    window_length: i64,
    periodic: bool
) -> Result<Tensor<T>, TensorError>

Creates a Hann window tensor. The Hann window is a taper formed by using a raised cosine with α = β = 0.5.

Parameters:

window_length: The length of the window

periodic: If true, returns a window to be used as periodic function. If false, returns a symmetric window

Returns:

A 1-D tensor containing the window.

Examples:

use hpt::{error::TensorError, ops::WindowOps, Tensor};
fn main() -> Result<(), TensorError> {
    // Create a periodic Hann window of length 5
    let a = Tensor::<f32>::hann_window(5, true)?;
    println!("{}", a);
    // [0.0000, 0.3455, 0.9045, 0.9045, 0.0000]

    // Create a symmetric Hann window of length 5
    let b = Tensor::<f32>::hann_window(5, false)?;
    println!("{}", b);
    // [0.0000, 0.5000, 1.0000, 0.5000, 0.0000]

    Ok(())
