As far as I know Matlab is x86 only, of course you can generate c code from Matlab but that has its own challenges.

To develop applications for the Raspberry Pi to be used in standalone operation, please see the Raspberry Pi Support from Simulink®." and of course, we're not using Simulink ==================== There's always a catch, isn't there! Perhaps this helps? https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=153608 "The open source "Octave" package is a Matlab clone and is the Raspbian repository. We've run a large base of Matlab code on Linux Octave with little or no change. One significant catch is that the version in the Raspian repository is 3.x which does not have the graphical IDE enabled by default as do the 4.x versions. The later can be built on RPi (512k or better versions) by following the procedure in the Octave Wiki.

TVB, let us know if we're drifting here. yes, one could build Octave and run that - I use Octave a LOT, although in general, I like Matlab's plotting better than Octave - the default choices are better, so I wind up with lots of .m code to make the plots look right. Octave also doesn't have some of the Matlab toolbox stuff, although, as described in that forum thread, you can find some of it. More to the point, the Matlab code I need to run wasn't written by me, but by someone else, who's not available to do any of this adaptation to Octave. ALso, this kind of "track down a replacement or reconfigure" takes time, which is money - so you have a tradeoff between maybe finding a different processor board (which also takes time) that costs a bit more, but runs your code unchanged without porting to Octave. ANother thing I've noticed is that Matlab is a LOT faster than Octave for some operations, I've not bothered to figure out exactly what it is that makes the difference, but I've got a a bunch of stuff that I'm doing where I read in 10 million samples and process them (e.g. radio output in a VITA-49 VRT file) and that "read, parse, and store into a big array" is an order of magnitude faster on Matlab than on Octave (on the same computer). I'm using the GUI Octave, so maybe its JIT compiler isn't as sophisticated as Matlabs - or maybe more of the underlying functionality in Octave is in .m files, as opposed to invoking a compiled function. By the way, there apparently IS a way to run non-simulink Matlab code on the Pi or BB... for some (TBD) limited subset of Matlab, you can put it in a simulink "execute Matlab code" block; compile the Simulink model, then squirt it down to the BB or Pi. Pretty clunky to my mind.. but there it is. "With the MATLAB Function block, you can incorporate MATLAB code into your Simulink model." https://www.mathworks.com/help/simulink/ug/what-is-a-matlab-function-block.html?s_cid=srchtitle it doesn't allow plot, disp, figure - but I wouldn't be using those on the BB or Pi... Basically, it will generate C/C++ code, so anything that Matlab can compile to C code will work.
