Automatically convert algorithms to C/C++, HDL, and CUDA code to run on your embedded processor or FPGA/ASIC. MATLAB Mac version code is production ready, so you can go directly to your cloud and enterprise systems, and integrate with data sources and business systems. There’s no need to rewrite your code or learn big data programming and out-of-memory techniques. ![]() Scale your analyses to run on clusters, GPUs, and clouds with only minor code changes. Iterate until you’ve got the results you want, then automatically generate a MATLAB for macOS program to reproduce or automate your work. MAT LAB apps let you see how different algorithms work with your data. MATLAB toolboxes are professionally developed, rigorously tested, and fully documented. Whether you’re analyzing data, developing algorithms, or creating models, MATLAB is designed for the way you think and the work you do. It includes the Live Editor for creating scripts that combine code, output, and formatted text in an executable notebook.

And we want those, my machine learning training arrays are huge! In order to get LibSVM compiled on your 64-bit Matlab version on a Mac, I thus changed the commands in make.m to: o files, and secondly, it doesn’t support 64 bit arrays. First of all, the make.m file provided with LibSVM expects. Unfortunately, this doesn’t work nicely either. Now, mex -setup finally works, and we can move onto building LibSVM. They actually do a very good deal describing the Mex woes Mac users will encounter when ‘upgrading’ to Xcode 4.3. Instead, it ships with a similar compiler (gcc-4.2 front-end to LLVM), that Matlab can use IFF you download and apply a patch from the Mathworks. Xcode used to ship with that, but no more. Sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/Īnd that’s that. But hey, I’m root on this machine, so let’s just bring it back: I suspect it always was in a more complicated sounding directory than /Developer, and /Developer just used to be a symlink to that. Instead, it’s found in /Applications/Xcode.app/Contents/Developer/Platforms/ First of all, for some obscure reason, Apple has done away with the /Developer directory. So, we’re fine, right? Surely Matlab will work fine now, right? Wrong again. Look for Command Line Tools, and click on install. Here’s how to get them (back): in Xcode: Preferences -> Downloads With "Components" selected, you will see a list of downloadable components. As I have version 4.3 installed, that means me. They have removed the command line utilities from their standard Xcode install as of version 4.2. What the? No gcc? How’s that possible? I had just installed the latest shiny Xcode, everything should be a-ok! But noooo, apparently Apple believes that real developers don’t need command line tools anymore. Applications/MATLAB_R2011b.app/bin/mex: line 305: gcc-4.2: command not found ![]() Note that LibSVM itself is now at version 3.11, but I haven’t been able to find out if there are any significant changes between 3.0-1 and 3.11 that would warrant me changing over.Īnyway, after downloading and unpacking the LibSVM files, I tried to set up my fresh Matlab installation to use the correct compiler. I use the version provided by UC Berkeley, which is based on LibSVM 3.0-1 but includes the Histogram Intersection Kernel, useful for my work with LBPs and other histogram-based appearance descriptors. One of the things I need for my day-to-day research is the Matlab version of LibSVM. I heard some bad stories about backwards compatibility issues of Lion, but heck, they’ve had plenty of time to sort that out, right? Wrong. So, I’ve finally received my super-hot new 15” MacBook Pro, and I’m super happy with it! Although slightly reluctant about upgrading to Lion and Xcode 4, I thought this would probably be the best moment to do it. ![]()
