Class Cm128DeMatMultDispatchConfigs

java.lang.Object
org.flag4j.linalg.ops.dispatch.configs.Cm128DeMatMultDispatchConfigs
public final class Cm128DeMatMultDispatchConfigs extends Object

A utility class for configuring dynamic kernel dispatch thresholds for complex dense matrix multiplication.

If a configuration file ./configs/CmDeMatMult.properties is present, settings will be loaded at class initialization. If not, default values will be used.

Thread Safety:

This class is designed to be thread-safe.
