My Matlab Expo 2016 keynote presentation (32:45) (Matlab Expo 2017 presentation will be different).
MathWorks were very kind to invite me to speak at the upcoming annual.
PicsArt Photo Studio Collage, view all Android apps, popular Windows Apps.My presentation will highlight several simple-to-use tips and tricks that can improve Matlab program usability and performance, and Matlab programming productivity in general.On doing this, my laptop did it.17 seconds and so the 2 core mode is almost exactly 2 times faster.Dont try to interact with matlab at all during the parallel portion of your code.Version: 2014, release date:, software type: Application Software, operating system: Windows 8; Windows 7; Windows Vista; Windows XP (SP3) 32-bit; Windows Server 2008 R2 64-bit; Windows Server 2003 R2 32-bit.I also presented at last years Expo in Munich (you can see the video on the right).We have implemented such an example in the mex function mex_sum_openmp.Move away from the golden rule, however, and youll find dragons. .Its also not quite as difficult as we originally thought it might.H double spawn_threads(double x,int cols) double sum0; int count; #pragma omp parallel for shared(x, cols) private(count) reduction sum) for(count 0;count cols;count) sum return sum; void mexFunction(int nlhs, mxArray* plhs, int nrhs, const mxArray* prhs) double sum; Check for proper number of arguments.Slowly but surely more and more matlab functions are becoming able to take advantage of multi-core processors. .
My aim is to show that Matlab can be used to create professional-quality applications, without sacrificing Matlabs benefits (RAD, functionality, reliability and that Matlab is certainly relevant for serious user-facing applications, not just for prototyping and internal organizational use.
