WebAug 31, 2024 · Running the conjugate gradient, the algorithm terminates in 5 steps. We examine the error in the residual by computing the sum of the absolute residual components. Note that this is not the error in the solution but rather the error in the system. We see that the error drops sharply at 4 iterations, and then again in the 5th iteration. … Webarticle “An Introduction to the Conjugate Gradient Method Without the Agonizing Pain”.
