Class BenchmarkMatrix

java.lang.Object

cern.colt.matrix.bench.BenchmarkMatrix

public class BenchmarkMatrix
extends Object

Configurable matrix benchmark. Runs the operations defined in main(args) or in the file specified by args. To get this overall help on usage type java cern.colt.matrix.bench.BenchmarkMatrix -help. To get help on usage of a given command, type java cern.colt.matrix.bench.BenchmarkMatrix -help <command>. Here is the help ouput for the dgemm command. Here is a sample result. For more results see the performance log.
