MATLAB engine benefits

Hello all,

I have never used the MATLAB engine from C before. I have a very basic
question:

What exactly is the benefit of this? To provide some more detail, for
example, if I were to perform a conjugate multiply of two very large
arrays, MATLAB would typically barf because of "out of memory" issues.
Would running MATLAB functions "behind the scenes" by invoking the
engine help in this regard?

I realize the speed up of the process here instead of having to
rewrite the MATLAB function in C but I wonder if my large data files
will run through better of will it have the same problem.

Thank you.

If that's all you're doing, look up the JAMA or TNT engines on the NIST 
web site, or find one of the other C-compatible numerical toolkit ports.

I could see some use if you were using some of the bells and whistles 
that MATLAB provides, but if you're just using LINPACK or EISENPACK 
functions, go with the real deal.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.

None. MATLAB is for stupidents. It is the entity beyond the necessity.
