2. “Moh’d Sami” AshhabSummer 2008University of Jordan 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 http://www.mathworks.com.

11. “Moh’d Sami” AshhabSummer 2008University of Jordan 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. “Moh’d Sami” AshhabSummer 2008University of Jordan 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. “Moh’d Sami” AshhabSummer 2008University of Jordan 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. “Moh’d Sami” AshhabSummer 2008University of Jordan 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. “Moh’d Sami” AshhabSummer 2008University of Jordan 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. “Moh’d Sami” AshhabSummer 2008University of Jordan 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. “Moh’d Sami” AshhabSummer 2008University of Jordan 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. “Moh’d Sami” AshhabSummer 2008University of Jordan 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 excel, text, ascii and dat. 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. “Moh’d Sami” AshhabSummer 2008University of Jordan 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.
