non-linear differential equations with non-constant coefficient
Hy, I'm a french student and I need to solve a beautyful equation, this could be an exemple : g(t)*sin(f(t)+B(t))+h(t)*cos(B(t))+d²(B(t))/dt²=0 g, h and f are known and I need B. I know that I won't be able to find an analytic solution, but I would like to use a numeric solution. I'm a beginner in matlab, I real... 28 Feb 2010 23:21

help with varargout
Dear all I am having some problems using varargout.I red the documentation but it seems that I am missing something. This is my code: varargout = myfunc(theta, data, type) % if type = 1 the function should produce two output arguments, say v1 and v2 % while if type = 2 there are three outut arguments, v3, v4... 28 Feb 2010 07:48

How can I solve a equation, which is mixing of ODE and PDE
I have to solve a equation, which is mixing of ODE and PDE. (dx/dt)+c(dx/dr)+d(dx/dk)=(dx(k)/dt) This equation has initial value at t=0. Right hand side is ODE, and it is in the form dx(k)/dt=c1*x(k), where c1 is constant. How can I solve this equation? Thanks for any further help Sunipa ... 1 Mar 2010 04:47
