References 2. The conjugate gradient method¶ 2.1. Introduction¶ For convenience, we start by importing some modules needed below: import numpy as np import matplotlib ... The conjugate gradients method solves for Ax=b when A is SPD. If A is not SPD, like in your case, then you can still use conjugate gradients to find the least squares solution for your problem: A^t A x = A^t b. The matrix A^t A is SPD and well suited for your method. In this example we follow An Introduction to the Conjugate Gradient Method Without the Agonizing Pain and demonstrate few concepts in Python. I shamelessly quote the original document in few places. References to equations and figures are given in terms of the original document. Abstract The Conjugate Gradient Method is an iterative technique for solving large sparse systems of linear equations. As a linear algebra and matrix manipulation technique, it is a useful tool in approximating solutions to linearized partial dierential equations. However, coming back to the title of this post: the conjugate gradient in python. The conjugate gradient is, as far as I know, the best method to minimize systems of linear equations such as (1) where is our forward model, the observable and our variable of interest. The conjugate gradient converges quadratically, which makes it an outstandingly fast. ConjugateGradients. Implementation of Conjugate Gradient method for solving systems of linear equation using Python, C and Nvidia CUDA. Currently only Python implementation is available - it includes Conjugate Gradient Method and Preconditioned Conjugate Gradient with Jacobi pre-conditioner (hopefully others will be added as well). conjugate gradient method implemented with python.
