Class FlatMatrix

java.lang.Object

com.github.gbenroscience.parser.turbo.tools.vector.matrix.FlatMatrix

public class FlatMatrix
extends Object

High-Performance Mechanically Sympathetic Flat Matrix (Non-Vector API Variant). * Bypasses explicit incubator vector instructions while structurally maximizing HotSpot JIT compiler loop auto-vectorization (SLP) via linear stride-1 alignment. * @author GBEMIRO
