Syntax

Copy

public double DropTolerance { get; set; }

Property Value

Double

Exceptions

Exception	Condition
ArgumentOutOfRangeException	Thrown if a negative value is provided.

Remarks

The values should always be positive and can be larger than 1.0. A low value will keep more small numbers in the preconditioner matrix. A high value will remove more small numbers from the preconditioner matrix.

Note that any changes to the DropTolerance after creating the preconditioner will invalidate the created preconditioner and will require a re-initialization of the preconditioner.
