Sorted by: 2. You can use an anonymous function instead of the function handle @fun. Then you can define the variables A1 and A2 inside the anonymous function like this: [X OUT] = ode45 (@ (x,s)fun (A1,A2,s),x_span,ic) Note that the function passed to ode45 needs two arguments. Since you don't need x in your function fun you just don't need to.

Hi everyone I'm a newbie in **matlab**, faced this issue: The model is **solving** first order **differential** equasion of a transient process in the RL branch Press J to jump to the feed. Press question mark to learn the rest of the keyboard shortcuts. The ODE **solvers** in **MATLAB** ® solve these types of first-order ODEs: Explicit ODEs of the form y = f ( t, y). Linearly implicit ODEs of the form M ( t, y) y = f ( t, y), where M ( t, y) is a nonsingular mass matrix. The mass matrix can be time- or state-dependent, or it can be a constant matrix. For **solving** the system of **equations** using the substitution method given two linear **equations** in x and y, express y in terms x in one of the **equations** and then substitute it in 2nd **equation**. Consider. 3x − y = 23 → (1) 4x + 3y = 48 → (2) From (1), we get: y = 3x − 23 → 3. Plug in y in (2), 4x + 3 (3x − 23) = 48. **MATLAB**® supplement that gives basic codes and commands for **solving** **differential** **equations**. **MATLAB**® is not required; students are encouraged to utilize available software to plot many of their solutions.

Differential-algebraic equations (DAE) contain amixture of differential (f) and algebraic equations, (g), the latter e.g. for maintaining mass-balance con-ditions:y0 =f(t,y,p) 0=g(t,y,p) Important for the solution of a DAE is its index.The index of a DAE is the number of differentiationsneeded until a system consisting only of ODEs is ob-tained.

The degree of a partial differential equation is the degree of the highest order derivative which occurs in it after the equation has been rationalized, i.e made free from radicals and fractions so for as derivatives are concerned. in (1.1.2), equations (1),(2),(3) and (4) are of first degree while equations(5) and(6) are of second degree.

The well known dmrode solver (Neves (1975)) was the first effective software for delay differential equations. Many of the central ideas on which this solver was based were used in later f77 solvers dklag5 (Neves & Thompson (1992)) and dklag6 (Corwin, Sarafyan, and Thompson (1997)), and the Fortran 90/95 dde_solver (Thompson & Shampine (2006)).
