Class LSODAExt

  • All Implemented Interfaces:
    org.apache.commons.math3.ode.FirstOrderIntegrator , org.apache.commons.math3.ode.ODEIntegrator 
    
public class LSODAExt
extends LSODA

    Extended LSODA solver that supports configurable maximum internal steps. The upstream lsoda-java library hardcodes mxstep=1000000 inside the lsoda() method, ignoring any reflection-based field setting. This subclass overrides integrate() to call the public lsoda() method directly with the desired mxstep value.

        LSODAExt(double minStep, double maxStep, double rtol, double atol, int meth, int miter, int maxSteps)
        Create an LSODAExt solver with configurable max steps.
        Parameters:
        minStep - minimum step size (absolute value)
        maxStep - maximum step size (absolute value)
        rtol - relative tolerance
        atol - absolute tolerance
        meth - method flag (12 = nonstiff/stiff auto)
        miter - iteration method (5 = diagonal Jacobian)
        maxSteps - maximum number of internal steps (replaces hardcoded 1000000)
