Detailed Description

Options for compute().

Member Data Documentation

iterations

int powerit::Options::iterations = 500

Maximum number of iterations to perform. Note that the algorithm may converge before reaching this limit.

num_threads

int powerit::Options::num_threads = 1

Number of threads to use for the matrix multiplication in compute(). The parallelization scheme depends on the definition of the #POWERIT_CUSTOM_PARALLEL function-like macro.

For compute_core(), the parallelization scheme depends on the provided multiply(), and this option has no effect.

tolerance

double powerit::Options::tolerance = 0.000001

Tolerance used to determine convergence. The error is defined as the L2 norm of the difference between eigenvectors at successive iterations; if this drops below tolerance, we assume that the algorithm has converged.
