To run the binary on Compute Canada servers, you will only need the binary. The wrapper script named <tt>run_cosplot.sh</tt> will not work as is on our servers because MATLAB assumes that some libraries can be found in specific locations. Instead, we provide a different wrapper script called <tt>run_mcr_binary.sh</tt> which sets the correct paths. | ||
