v0.36.1

Release 0.36.1 (2024-04-09)

• Fix all warnings in peroxide

• Change redundant method

  • Vec<f64>::resize -> Vec<f64>::reshape

• Error handling for concatenation

  • cbind & rbind now returns Result<Matrix, ConcatenateError>

• New non-macro utils

  • column_stack(&[Vec<f64>]) -> Result<Matrix, ConcatenateError>
  • row_stack(&[Vec<f64>]) -> Result<Matrix, ConcatenateError>
  • rand_with_rng(usize, usize, &mut Rng) -> Matrix

• Generic Butcher tableau trait (now for embedded Runge-Kutta methods)

  pub trait ButcherTableau {
      const C: &'static [f64];
      const A: &'static [&'static [f64]];
      const BH: &'static [f64];
      const BL: &'static [f64];
  
      fn tol(&self) -> f64;
      fn safety_factor(&self) -> f64;
      fn max_step_size(&self) -> f64;
      fn min_step_size(&self) -> f64;
      fn max_step_iter(&self) -> usize;
  }

  • Implement ODEIntegrator for ButcherTableau

    • Just declare ButcherTableau then step is free

  • Three available embedded Runge-Kutta methods

    • RKF45: Runge-Kutta-Fehlberg 4/5th order
    • DP45: Dormand-Prince 4/5th order
    • TSIT45: Tsitouras 4/5th order
