Suppose in matlab the following: [t, x, te, xe, ie] = ode15s(@myfunc, [tStart开发者_高级运维 tFinal], x0, odeset(\'Events\', @events));
Given the following code: s := NDSolve[{x\'\'[t] == -x[t], x[0] == 1, x\'[0] == 1}, x, {t, 0, 5 }] Plot[Evaluate[{x[t]} /. s], {t, 0, 3}]
More specifically, i\'m interested in 8th order Dormand开发者_如何学JAVA-Prince embedded method, it\'s based on Runge-Kutta, and stiff equations.
The problem: I am trying to solve this diffrential equation: K[x_, x1_] := 1; NDSolve[{A\'\'[x] == Integrate[K[x, x1] A[x1], {x1, 0, 1}],
I\'m trying to input a second order differential equatio开发者_C百科n to solve into matlab over x = 0 to x =1. I can\'t figure out how. Here\'s the equation:
Im working on a program in python that takes approximately 100 inputs and generates around 500 outputs.There are many calculations that have to be done in the middle and I am having several problems w
I have differential equations derived from epidemic spreading. I want to obtain the numerical solutions. Here\'s the equations,
My application has some parabolic partial differential equations...which are inter-related and use some variables which the user inputs via a UI from a desktop application.
I\'m working on mapping a temperature gradient in two dimensions and having a lot of trouble. My current approach is to define an Interpolating Function and then try to graph it a lot of times, then a
I\'m trying to develop a physics simulation and I want to implement a fourth-order symplectic integration method. The problem is that I must be getting the math wrong, since my simulation is not worki
