Function dst2 

pub fn dst2<T>(
    x: &ArrayView2<'_, T>,
    dst_type: Option<DSTType>,
    norm: Option<&str>,
) -> FFTResult<Array2<f64>>
where
    T: NumCast + Copy + Debug,

Compute the 2-dimensional discrete sine transform.

Arguments

• x - Input 2D array
• dst_type - Type of DST to perform (default: Type2)
• norm - Normalization mode (None, “ortho”)

Returns

• The 2D DST of the input array

Examples

use scirs2_fft::{dst2, DSTType};
use scirs2_core::ndarray::Array2;

// Create a 2x2 array
let signal = Array2::from_shape_vec((2, 2), vec![1.0, 2.0, 3.0, 4.0]).unwrap();

// Compute 2D DST-II
let dst_coeffs = dst2(&signal.view(), Some(DSTType::Type2), Some("ortho")).unwrap();
