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.

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.

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

ENG004.01 6

Programming

How to make a machine to perform the algorithms?

PROGRAMMING

How to program?

ENG004.01 7

You need some tools to make the machine perform your algorithms

Basic Pascal C,C++ Java Perl ...

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.

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?

ENG004.01 10

And now let’s see How MATLAB looks?

Follow me now!

ENG004.01 11

Let’s do some Calculations

The 4 basic calculation 1+2 5-1 15*2 8/4 (1+2)*5-1

ENG004.01 12

Gauss Number

1+2+3+...+100=?

Let’s use MATLAB

2

1....321

nnn

>> 100*(100+1)/2ans = 5050>>

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?
