In mathematics, a stiff equation is a differential equation for which certain numerical methods for solving the equation are numerically unstable Stiffness ratio · Characterization of stiffness · A-stability

An ordinary differential equation problem is stiff if the solution being sought is varying slowly, but there are nearby solutions that vary rapidly.

This page contains two examples of solving stiff ordinary differential equations using ode15s. MATLAB has four solvers designed for stiff ODEs.

contrast to the true solution. Facts: 1) A stiff differential equation is numerically unstable unless the step size is extremely small. 2) Stiff differential ...

7 мар. 2021 г. · A differential equation is stiff if a numerical scheme requires a very small time-step in order to be stable for that equation.
