Simulink Models

In the past the trend in simulation and modeling of a physical
system that uses a series of, say, partial differential equations was
this: You develop all these functions in C++. But writing hundreds
of lines of new code for each algorithm proved to be time-consuming
and impractical - even the object-oriented modular approach of
C++ coding did not provide much advantage. Maintenance of such
codes in this ever-changing world of software development turned
out to be taking time away from your first objective that you
started with - to understand that "physical system"!

The general trend nowadays is to use Simulink package of Matlab.
Simulink allows the users to write the algorithm quickly and
efficiently in a modular way. The various sections of the model and
the underlying equations are represented as functional blocks in
the software and can be easily manipulated by simply connecting
and arranging the blocks as required. It is also possible to create a
library of such models and then to easily combine them with some
newly developed ones and create a more complicated simulation
model.
