Question

Conjugate gradient method is implemented in _________

(a) Algorithm solving

(b) Iterative solving

(c) Program solving

(d) Program CG solving

This question was posed to me by my college professor while I was bunking the class.

My doubt is from Conjugate Gradient Method for Equation Solving in division Matrix Algebra and Gaussian Elimination of Finite Element Method

Answer 1

Correct choice is (d) Program CG solving

The best I can explain: Conjugate gradient algorithm procedure is implemented in program CG solving, which is included on disk. This method is also easily to solve in MAT Lab also. Several algorithms have been proposed e.g., CGLS, LSQR.
