![]() ![]() The Matlab example called magicsquare in the documentation can be used as an example. You will need to load the MCR version corresponding to the Matlab version you used to compile your standalone executable. Is Matlab MCR available to run compiled jobs? Yes. What do I need to know? Your jobs will end up on a partition with a limit of 512 concurrent jobs/cores/user. I want to run hundreds of matlab jobs using my matlab scripts. This will take several minutes and should result in five passed tests. To test this out, you may run the Validation tests by choosing Start Validation. warp="matlab -nojvm -nodisplay Import Cluster Profile and browse to the config file. ![]() * SUM_FIRST_N_MEX sums the first N integers % SUM_FIRST_N_LOOP sums the first N integers, loop form % SUM_FIRST_N_VECT sums the first N integers, vectorial form Vectorized notation type sum_first_n_vect.m Second example: The sum of the first N integers It is possible to use debugger tools, but this is for another tutorial. To stop the execution, you need to kill Matlab, so make sure you properly save your data before launching possibly long simulations. You cannot interrupt execution of a mex-file from within Matlab ( Ctrl-C does not work). Mex-files are pre-compiled, if you have bugs, Matlab will not be able to tell you where the error is. The executable can be called as any other Matlab function.
