Struct LstsqResult 

pub struct LstsqResult<S, R>
where
    S: Scalar,
    R: Scalar,
{
    pub solution: Tensor<S>,
    pub residuals: Tensor<R>,
}

Least-squares result.

Examples

use tenferro_linalg::lstsq;
use tenferro_prims::CpuContext;
use tenferro_tensor::{MemoryOrder, Tensor};

let mut ctx = CpuContext::new(1);
let a = Tensor::from_slice(&[1.0_f64, 0.0, 1.0, 1.0], &[2, 2], MemoryOrder::ColumnMajor)
    .unwrap();
let b = Tensor::from_slice(&[1.0_f64, 2.0], &[2], MemoryOrder::ColumnMajor).unwrap();
let result = lstsq(&mut ctx, &a, &b).unwrap();
assert_eq!(result.solution.dims(), &[2]);

Fields

solution: Tensor<S>

Least-squares solution.

residuals: Tensor<R>

Squared residual summaries ||AX - B||_F^2 per right-hand side, or an empty tensor.
