Struct LstsqGrad

Source

pub struct LstsqGrad<T: Scalar> {
    pub a: Tensor<T>,
    pub b: Tensor<T>,
}

Expand description

Gradient result for lstsq_rrule: cotangents for both A and b.

§Examples

use tenferro_linalg::LstsqGrad;
use tenferro_tensor::{MemoryOrder, Tensor};

let grad = LstsqGrad {
    a: Tensor::<f64>::zeros(&[2, 2], tenferro_device::LogicalMemorySpace::MainMemory, MemoryOrder::ColumnMajor).unwrap(),
    b: Tensor::<f64>::zeros(&[2], tenferro_device::LogicalMemorySpace::MainMemory, MemoryOrder::ColumnMajor).unwrap(),
};
assert_eq!(grad.a.ndim(), 2);
assert_eq!(grad.b.ndim(), 1);

Fields§

§a: Tensor<T>

Cotangent for the system matrix A.

§b: Tensor<T>

Cotangent for the right-hand side b.
