2. ENG004.01 2 The class facts E-mail address: iku.eng004.01@gmail.comiku.eng004.01@gmail.com Class web page: http://web.iku.edu.tr/courses/insaat/eng004/ http://web.iku.edu.tr/courses/insaat/eng004/

3. ENG004.01 3 Last week The syllabus was distributed. The facts about the class was mentioned The class e-mail was introduced and the students were asked to send a registration mail to the class e-mail.

4. ENG004.01 4 This week What is Algorithm and Programming? Why do we need programs? A powerful tool- MATLAB What is MATLAB? Why MATLAB? HOw to use it? The first commands in MATLAB.

5. ENG004.01 5 Algorithm and Programming The best way to do some work is to know how to do it. ALGORITHM Some examples to Algorithm

6. ENG004.01 6 Programming How to make a machine to perform the algorithms? PROGRAMMING How to program?

7. ENG004.01 7 You need some tools to make the machine perform your algorithms Basic Pascal C,C++ Java Perl...

8. ENG004.01 8 MATLAB MATLAB (MATrix LABoratory) is a powerful program based on C++ and JAVA applications. It has wide range of command library. Almost every engineering student in USA uses MATLAB. Most of the Turkish Universities started teaching MATLAB in introductory classes.

9. ENG004.01 9 MATLAB and Columns-Beams? What is the relationship? MATLAB in Civil Engineering?  Do we need it?  Does any Civil Engineer use MATLAB in work?  Have you ever seen any Civil Engineer using MATLAB?

10. ENG004.01 10 And now let’s see How MATLAB looks? Follow me now!

11. ENG004.01 11 Let’s do some Calculations The 4 basic calculation  1+2  5-1  15*2  8/4  (1+2)*5-1

12. ENG004.01 12 Gauss Number 1+2+3+...+100=? Let’s use MATLAB >> 100*(100 +1)/2 ans = 5050 >>

13. ENG004.01 13 Assignment #1 Please do the following calculations in MATLAB >> 10*(10+1)/2 >> (10+50)*(10+20)/10 >>10*(10+1)+(10+1/2)*(58+1) >>25/2+8-9 >>8+9*9-5 >> 8+9*(9-5) >> (8+9)*9-5 Are there any difference between these calculations?
