Hi,
You can try using mpilibconf function to locate the path of MPI library if it is installed . Try using
doc mpilibconf
to get the documentation mpilibconf
and if library is not installed you can try installing your own MPI library online.
you can change the system path would be to specify the full path to your MPI library in the mpiLibConf.m file itself. For example:
function [lib, extras] = mpiLibConf
extras = {};
hope it helps,
thanks.
