Density gradient method
of sperm preparation appeared to be more efficacious in percentage recovery of motile sperm concentration compared to swim-up method.
Compared with the new joint Newton iteration and Neumann series method, conjugate gradient method
 and GS method  converge faster, but they approximate [W.
The conjugate gradient method
is popular for solving large scale optimization problems.
We give comparisons between the Galerkin projection approach (GA) and the minimal residual (MR) approach for large-scale problems using the global LSQR (Gl-LSQR), the preconditioned global conjugate gradient method
(PGCG), the direct Kronecker product when solving the reduced least squares minimization problem, and the Hu-Reichel method (HR).
A spectral conjugate gradient method
for unconstrained optimization.
Analysis of linear programming gradient method
for optimal design of water supply network.
the position vector of the observer, we obtain the exact expression of angular glint at near field based on phase gradient method
, and show that the expression in  is the far-field approximation of ours under certain polarization.
One is the inner iteration that completes the source reconstruction by solving (7) via the conjugate gradient method
If the gradient and Hessian are both available, then the inverse approach is known as a Newton method; if only the gradient is available, then it is a gradient method
The horizontal gradient method
was used to locate density boundaries from gravity data (Cordell and Grauch, 1985).
Conjugate gradient method
 is a well known method for solving large number of equations.
2 is solved by the preconditioned conjugate gradient method
, which is applicable to solve system of large scale complex linear equations.
