torch.geqrfIt is a function in PyTorch used to compute the QR decomposition of a matrix, returning the Q and R matrices.

Function Definition

torch.geqrf(input)

Returns:

  • a - Orthogonal matrix Q
  • tau - Factor required to produce the orthogonal matrix

Usage Example

Example

import torch

# Create matrix
A = torch.randn(3, 3)

# QR decomposition
a, tau = torch.geqrf(A)
print("a (Q):", a)
print("tau:", tau)
