Interface C++ functions/Simulink
Hello, I'm working on a vision based tracking system for UAVs. I am using Shawn Lankton's implementation of the Sparse Field Method for Active Contours (http://www.mathworks.co.uk/matlabcentral/fileexchange/23847-sparse-field-methods-for-active-contours) and I would like to adapt it to use it in Simulink. This im... 1 Jun 2010 20:49

fsolve problem
I am using Matlab 7.6.0.324, and I find that I am having problems using fsolve to solve a system on two non-linear equations in two unknowns. I am relatively new to Matlab, so I apologise in advance if I seem inexperienced. I am. Basically when I call my M-file myfun.m within the main command window i.e. when I type ... 19 May 2010 12:40

nonlinear differential equation system
Hi, i'm trying to solve this nonlinear differential equation system: T' = (Rtes*Is.^2-k*(T.^5-Ts.^5)+epsilon*E*dirac(t-t0))./C; Is' = (Ib*Rsh-Is.*(Rp+Rtes+Rsh))./L; T and Is are function of time, like dirac(t-t0). I declare the system in a M-file where i give the value of the other parameters. Here ie the code... 20 May 2010 10:32

parse expression into expression tree
Hi, I need to parse a math expression like (a+b)/c + d into an expression tree and traverse the tree in various orders (in order, preorder, postorder). Are there existing toolboxes/functions in matlab to do that? I looked at the symbolic toolbox but haven't found anything close to that. thanks Jeff ... 19 May 2010 11:33

Concentration maps
Hello everybody, I have a problem and I think that it should be easy to solve but for some reason I do not manage that. I have arrays containig latitude, longitude and concentration values. I wanna plot the concentration values at the corresponding lat/lon point in different colours for different concentration v... 26 May 2010 09:08
