Thrread in Matlab

Please don't highlight your own messages, the board software handles that.

Yes, matlab can do parallel processing

Implicit Multiprocessing

Characteristics of implicit multiprocessing:

*

Runs multiple threads on a single machine, most often using one thread per processing unit.
*

Requires a multiple CPU (multiprocessor or multicore) system.
*

Speeds up elementwise computations such as those done by the sin and log functions, and computations that use the Basic Linear Algebra Subroutines (BLAS) library, such as matrix multiply.
*

Does not require any changes to your MATLAB code.
*

Works behind the scenes to take advantage of the processing units available to you. It does this by multithreading the computationally-intensive math library functions that you use in the course of your MATLAB session.

MATLAB enables multithreaded computation by default. You can disable it by specifying the singleCompThread option when starting MATLAB.
Explicit Multiprocessing

Characteristics of explicit multiprocessing:

*

Runs separate processes on one or many machines.
*

Requires installation of Parallel Computing Toolbox.
*

Speeds up execution of large MATLAB jobs. Enables you to run jobs simultaneously on a cluster of computers, or as several processes on a single machine.
*

Requires that you modify your MATLAB code.
*

The Parallel Computing Toolbox supports programming constructs for distributed arrays and parallel for (parfor) loops. It also supports both interactive and batch execution.

Enable explicit multiprocessing by installing Parallel Computing Toolbox.

However, if you only have one drive and you're memory swapping while writing to a file, there will be contention for resources.
