To solve differential equations, use the dsolve function. When solving a system of equations, always assign the result to output arguments. Output arguments let you access the values of the solutions of a system.

Use MATLAB® to formulate and solve several different types of differential equations. MATLAB offers several numerical algorithms to solve a wide variety of differential equations: Calculate Tangent Plane to Surface Approximate gradients of a function by finite differences.

These prices are set using equations that determine how many items to make and whether to rais Customers don't care about a 'buyer's journey' or your internal org chart. They only care about their success -- and that's what you should care the most about, too. Overview of all products Overview of HubSpot's free tools Marketing automa The key to happiness could be low expectations — at least, that is the lesson from a new equation that researchers used to predict how happy someone would be in the future. In a new study, researchers found that it didn't matter so much whe Study of ordinary differential equations (e.g., solutions to separable and linear first-order equations and to higher-order linear equations with constant coefficients, systems of linear differential equations, the properties of solutions t Study of ordinary differential equations (e.g., solutions to separable and linear first-order equations and to higher-order linear equations with constant coefficients, systems of linear differential equations, the properties of solutions t Numerical methods for ordinary differential equations are methods used to find numerical Numerical methods for solving first-order IVPs often fall into one of two large categories: linear multistep methods, Quantized state systems deal with the large, complicated, and nonlinear systems of equations seen in practice. This book is about solving ODEs numerically.

What you are outlining in your question (parallel) are so-called coupled differential equations. x1 and x2 - or rather, their time derivatives - are functions of each other. The only way to solve these kinds of equations is by solving them, as you said, in parallel. And that's accomplished in MATLAB by using e.g. ode45.

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