MPIBCAST MPI Broadcast

Usage

This function is used to broadcast an array to all group members. The syntax for its use

  B = mpibcast(A,root,comm)

where A is the array to broadcast, root is the rank of the root of the broadcast, and comm is the communicator to do the broadcast on. If no communicator is provided, it defaults to MPI_COMM_WORLD. Note that in practice, the process running at the root will use the syntax:

  mpibcast(A,root,comm),

while the remaining processes will use the syntax

  B = mpibcast([],root,comm).
