Solution:

This enhancement has been incorporated in Release 2007a (R2007a). For previous product releases, read below for any possible workarounds:

The MathWorks products are qualified and supported on the Intel® Core™ Duo family of processors which includes Intel® Core™ 2 duo.

For MATLAB 7.4 (R2007a), multithreading capabilities can be enabled. If you run MATLAB on a multiple-CPU system (multiprocessor or multicore), you can use multithreaded computation, which can improve performance for some operations. MATLAB can take advantage of multithreading capabilities for element-wise numerical computations such as "sin" and "log", and BLAS (Basic Linear Algebra Subroutines) library computations such as matrix multiply. For more information, execute the following at the MATLAB command prompt:

For previous versions read below:

MATLAB is a single threaded application. However, multiple processors can be utilized by the BLAS (Basic Linear Algebra Subroutines), if the BLAS version being used supports multi-threading. In this case, significant performance improvement may be observed when running linear algebra intensive applications. This can be achieved on MATLAB 7.3 (R2006b).
