发帖数: 921 | 34 I want to solve a system of ODE, for example,

for x3, it satisfy, x1^2 + x2^2+x3^2=10;
my code is below:
function xp = F(t,x)
xp = zeros(3,1);
xp(1)= x(2) -x(1)^2+ x(3)^3;
xp(2) = - x(1)*x(3) - 2*x(1)*x(2) + x(3);
x(3) = sqrt(10-x(1)^2-x(2)^2);
[t,x]=ode45(@F,[0,10],[0;1;1]);

my figure shows x3 is a straight line, what is the mistake?

发帖数: 401 | 43 The unknown function f(x,y) is defined in the area of x>=0 and y>=0, i.e.,
in the first quadrature. For any x,y, f(x,y) >= 0.
f(x,y) is characterized by the following PDE,
df(x,y)/dx + df(x,y)/dy = A(x)B(y) + C(x)D(y), where A and C are known
functions of x, and B and D are known functions of y.
This seems to be a inhomogenous first-order linear PDE. The function f looks quite similar to the wave equation, but the AB+CD term seems hard to handle. Is there a way to analytically solve the problem? |
