Hi there: I am having a tough time integrating odes on my GPU in MATLAB. I have tried MATLAB ode solvers which, of course, didn't work. I tried a simple Euler solver to execute through 'arrayfun' which didn't worked either. It looks like a lot of functionality is not yet supported for computation on GPUs. Please help me out if I am not aware of something or if there is an easy way out. I am running MATLAB R2011b on Windows 8. Thanks, Shiv

I have the same problem, parfor is a good option, but i need more power, If somebody knows how to implement ode in gpu would be great,

I am also in need of an ode in gpu and was wondering if any resources are available in MATLAB?

Higher matlab versions includes more functions, but still too few to solve an ODE or a PDE. Arrayfun is a good tool with unexpected flaws. The best way to implement an ODE solver on GPU with matlab is matlab-with-CUDA. First you write the parallel parts in CUDA (.cu file) and compell out a '.ptx' file using whatever method. Then with the .cu and .ptx file, you can obtain a matlab parallel function. You will get more from the Parallel Computing Toolbox introduction document of matlab.

Have you made any progress Shiv?! I could not find any material regarding CUDA and ODE for Matlab! Any help is appreciated.

Dear Hamid,
Please inspect the error message below when running Test_02_RTBP.m in your github repo:
"
Error using gpuArray/arrayfun
Unable to resolve the function handle.
Error in Test_02_RTBP (line 36)
[TGPU,YGPU1,YGPU2,YGPU3,YGPU4,YGPU5,YGPU6,FLAG] =
