Still, even with a high Java heap space setting and lots of RAM, Matlab crashed after using my program for several hours. Greedy algorithms take all of the data in a particular problem, and then set a rule for which elements to add to the solution at each step of the algorithm. We'll use this chunk of frames to try to detect the phase of the pulldown. OutOfMemoryError: Java heap space" when calling -- As others have said, you can reduce the memory requirements by using SXSSF and also using SS_freeLocalRef(Row) at least to clear each row from memory as its completed. The "hanging" is probably because INET and INETMANET's default setup uses all available CPU cores for building the respective projects. If the code that you'd like to compile does not use JVM functionality (you can verify this by starting MATLAB using "matlab -nojvm" from the system prompt and then running your code), you can compile your code using the mcc "-R -nojvm" option when compiling shared libraries or standalone applications.
