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.

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) Are there any difference between
these calculations?
>> (8+9)*9-5
