I'm looking to solve a system of the type dxdt=A*x where dxdt and x are 1xn vectors and A is an nxn matrix. I know I can use something like ode45 to solve each row individually, but figured matlab must have a way of solving such systems. Thanks in advance! 2020-06-21 Solve Differential Equation with Condition.

Solving differential equations in matlab

Create these differential equations by using symbolic functions. See Create Symbolic Functions. Solve differential algebraic equations (DAEs) by first reducing their differential index to 1 or 0 using Symbolic Math Toolbox™ functions, and then using MATLAB ® solvers, such as ode15i, ode15s, or solving single equations, where each scalar is simply replaced by an analogous vector. In particular, MATLAB speciﬁes a system of n PDE as c 1(x,t,u,u x)u 1t =x − m∂ ∂x It's not that MATLAB is wrong, its solving the ODE for y(x) or x(y). Exact differential equations is something we covered in depth at the graduate level (at least for engineers). It's helpful if you explain the math more before posing this as programming question. Without some explanation how f(x,y) is involved would not be clear.

Solving differential equations in matlab

Learn more about differential equations, nonlinear 2020-10-21 I am wondering whether MATLAB is able to solve DIFFERENCE (recursive) equations, not differential ones. For example, difference equations as those frequently encountered in Economics. 2020-05-10 2007-08-15 2021-03-31 Solving Delay Differential Equations. Delay differential equations (DDEs) are ordinary differential equations that relate the solution at the current time to the solution at past times.

It provides a complete narrative of differential equations showing the theoretical aspects of the problem (the how's and why's), various steps in arriving at solutions, multiple ways of obtaining solutions and comparison of solutions. If dsolve cannot solve your equation, then try solving the equation numerically. See Solve a Second-Order Differential Equation Numerically. Nonlinear Differential Equation with Initial Condition. Solve this nonlinear differential equation with an initial condition. The equation has multiple solutions.
