Introduction
to MATLAB
MATLAB, which
stands for MATrix LABoratory, is a mathematical software, which
is used extensively in both academia and industry.
It is an
interactive program for numerical computation and data visualization.
I think MALTAB
is very essential tool for every Engineer and Reseacher for doing their
research and scientific computation like image processing, data curve fitting
etc.
And not only for
these , you can also use MALAB for Finance, Biomatric(finger print recognition)
and speech recognition, live signal analysis and much more.
MATLAB is both computer programming language and software environment for
using that language effectively.
MATLAB is matrix-oriented, so what would take several statements in C or
Fortran can usually be accomplished in just a few lines using MATLAB's built-in
matrix and vector operations
So in MATLAB you
do not required to write any program, simply type command which you want to
see.
MATLAB is available for MS Windows, Macintosh personal computer, Unix and
other operating systems.
It is also available for Android mobile. Go to play store and search for
matlab mobile.
MATLAB includes hundreds of functions
for:
•
Data analysis
and visualization,
•
Numeric and
symbolic computation,
•
Engineering
and Scientific graphics,
•
Modeling,
simulation, and prototyping,
•
Eigenvalue,
singular value
MATLAB works with scalars, vectors and matrices:
•
Basic matrix
operations,
•
Inverses of
matrices,
•
Graphs of
matrices,
•
Matrix
manipulation,
•
Programming,
application development, and GUI design
MATLAB has remarkable graphics capacities:
•
2-D and 3-D
plots,
•
Line plotting,
•
3-D surface
plot,
•
Splash screen
plot
MATLAB has remarkable graphics
capacities, 3_D plots are some of them:
•
3-D plots in
Handel Graphics
•
Plot Type,
•
Shading,
•
Colomap
MATLAB has many toolboxes:
•

Analysis and ...
SIMULATION
- Simulink has the ability to simulate a large range of systems, from verysimple to extraordinarily complex. The Model and demonstrations that you will see in this section include both simple and complex systems.
- Used to model, analyze and simulate dynamic systems using block diagrams.Fully integrated with MATLAB , easy and fast to learn and flexible.
- It has comprehensive block library which can be used to simulate linear, non–linear or discrete systems – excellent research tools.
- C codes can be generated from Simulink models for embedded applications and rapid prototyping of control systems.
Simulink has the ability to simulate a
large range of systems, in the menu of Simulation we have:
•
Pause.
•
Stop,
•
