Bi |
public sealed class BiCgStab : IIterativeSolver<Complex32>
The BiCgStab type exposes the following members.
Name | Description | |
---|---|---|
Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) | |
GetHashCode | Serves as the default hash function. (Inherited from Object) | |
GetType | Gets the Type of the current instance. (Inherited from Object) | |
Solve | Solves the matrix equation Ax = b, where A is the coefficient matrix, b is the solution vector and x is the unknown vector. | |
ToString | Returns a string that represents the current object. (Inherited from Object) |
The Bi-Conjugate Gradient Stabilized (BiCGStab) solver is an 'improvement'
of the standard Conjugate Gradient (CG) solver. Unlike the CG solver the
BiCGStab can be used on non-symmetric matrices.
Note that much of the success of the solver depends on the selection of the
proper preconditioner.
The Bi-CGSTAB algorithm was taken from:
