在科学计算领域,特别是ODE类微分方程的求解,Julia已经实现并覆盖了最大部分的求解算法,相比于其他科学计算软件(MATLAB) 图片来源:https://www.stochasticlifestyle.com/comparison-differential-equation-solver-suites-matlab-r-julia-python-c-fortran/#:~:text=For%20the%20current%20state%20of%20the%20reproducibl...
When solving a differential equation, it's pertinent that your derivative function f is fast since it occurs in the inner loop of the solver. We can convert the entire ode problem to symbolic form, optimize that symbolic form, and emit efficient native code to simulate it using de.jit to ...
