HELLO_PARFOR is a directory which illustrates how a MATLAB function using the PARFOR statement can be run in parallel.
Here, the underlying MATLAB program is a simple function that says "Hello, world!" a certain number of times. The loop used to print these statements is controlled by a parfor command.
The function has the form:
function hello_fun ( n )where
Depending on the situation, the function could be executed in parallel:
