Open in MATLAB Online Hi, I'm new in Matlab. I'm trying to create quiver3 for ODE45 (for phase trajectories in the space xyz, I hope I'm using the right function for this), when I runing the code I don't get the
MATLAB Online에서 열기 Motivation: I am trying to learn how to use ode45 for fun after studying some math (because it seems engineering eventually makes you forget math and because I didn't have access to matlab in college many years ago)...
MATLAB Online에서 열기 I have written code (shown below) that uses ode45 to solve 2 differential equations to determine particle number during perikinetic and orthokinetic aggregation for a given flow rate (Reynolds number) through a static mixer. The ...
ode45(@f, t, [y0, dy0]) Help please? Accepted Answer Star Strideron 8 Oct 2019 0 Link Open in MATLAB Online You are almost there! Try this: dydt = @(t,y) [y(2); eps*((y(1)^2) - 1)*y(2) - y(1)]; ic = [1 1]*eps; ...

It looks like you're maybe expecting h to be changed after you exit the function, which will not be the case since all input arguments are "pass by value", not "pass by reference". I hope you know what those basic computer science terms mean. Thus your code is...

part about pdot and initials conditions. But the second part about y(1) and y1... What I mean is y(1) should then be an scalar not a variable. Because Y is a vector and setting dy(1) = y(2)*y(3) [for instance] would put the product of two scalars y(2) and y(3) in ...
