streaming in D2Q7 LB model
Hi, Recently I have been working on 2D LB models for my project. I have been able to code D2Q9 LB model, but now struggling to code the D2Q7, i.e., LB model with hexagonal lattice. Is there any freely available sample Matlab code on D2Q9? The major problems in D2Q7 I'm facing are to define Matrices with hexagona... 6 Oct 2009 04:49

idl2matlab
I have a bunch of IDL code that I am trying to implement in an external program. That program can understand Matlab code. I found IDL2MATLAB and have been trying to use it to translate my IDL code. I know it's installed correctly, because the included test works just fine, but when I go to translate my code I get a ... 6 Oct 2009 03:12

ODE Optimization
I am trying to optimize 8 paramaters in a set of ODE's for a least squares fit to a set of data. I am using fmincon to minimize the sum of squares between the numerical solution of the ODE's and the experimental data. I generated the experimental data from the ODE's so I already know the paramaters...in other words I... 7 Oct 2009 17:31

Problem with random
Hi, I have implemented Differential Evolution algorithm in Matlab. When I'm checking with the global optimization problems like Griewank, Branin, Rastringen etc. I am not getting the reported solution. I guess this with random number generation. I have changed the seed of the random number but still I'm not getting th... 5 Oct 2009 04:40
