Instance Property

maxIterations

Maximum number of iterations.

Declaration

var maxIterations: Int32

Discussion

If maxIterations is less that zero, a default value of 4n is used. However, if a good preconditioner is available and or the matrix is well conditioned such that singular values are clustered, a value of n/2 may be more appropriate.
