2. What is MATLAB The name MATLAB stands for Matrix Laboratory.
MATLAB is a matrix-based software system designed to assist in
scientific, engineering and business problem solving.
In this prsentation we will give you the opportunity to get
accustomed with the use of MATLAB in addition to its applications
and power.
Information about the software can be found at the MathWorks
web site .

11. 3. 2D Plots
Once you master Matlab basics, vectors and matrices, It becomes
simple process to generate 2-dimensional plots with MATLAB.
It is possible to control the appearance of the plots and use them in
other documents such as Microsoft word.
Some of the plotting features are:
- Curve color and style control
- Axis labeling
- Title Addition
Text Addition
- Grid, axis and legend features

14. 4. 3D Plots Matlab enables you to display
three dimensional information.
Surface and contour plots are possible.
One dimensional curves in the three
dimensional space can be generated.
Deep knowledge of matrix use is
needed to setup data for the plot.

19. 6. Logical Satements
The logical statements are very important in programming Matlab.
We will cover all the aspects that the user needs for logical statements
such as syntax, if-statements and logical operators.

20. 7. Loops The loops are very important in programming Matlab.
We will cover all the aspects that the user needs for loops
such as syntax for and while loops and break statement.

21. 8. Functions (Subroutines)
Matlab represents standalone functions in individual programs.
The user can program his own functions and add them to the
Matlab library.
The user can use his subroutines anytime in the future once he/she
has the stored in the Matlab libraries.
Subroutines are essential for
methods that require the
solution of a function
such as root finding and
differential equations.

22. 9. Solution of Linear Differential Eqs
Differential equations appear in most of the scientific, engineering
and business applications.
Matlab is a very powerful tool for the solution of linear
differential equations.
A Matlab user will solve the linear differential equations efficiently
when he/she understands how to convert these equations into
a matrix form.
In the Matlab training course we will cover the basics of linear
differential equations first and then Matlab will utilized to solve
all types of linear differential equations.

24. 10. Solution of Nonlinear Differential Eqs
Nonlinear differential equations are very hard to solve analytically
and therefore a computer program or software is needed.
Most of the differential equations that are encountered in
practical applications are nonlinear.
Matlab is one of the best available softwares
that can solve nonlinear differential equations
efficiently and fast.

25. 11. Handling Files
Matlab is able to extract data from files in formats such as
excel, text, ascii and dat.
Matlab generated data in Matlab is stored in the .mat (Matlab) format.
Matlab allows the user to store the data in formats such as
In summary, Matlab can exchange data in different formats and
and thus eliminating the need to entering the data by hand when
it comes from other various sources.

26. 12. Simulink Simulink is a nice and powerful tool that
represents a system as a block diagram.
Each block represents a component of
the system. These components are
interconnected to form the block diagram.
Block Diagrams are solved with Simulink.
People usually prefer using Simulink
over Matlab programming because it is
easier to monitor and understand the system.
