English-Tutorial-5: Arithmetic operation in MATLAB-2013a

Arithmetic operation:

For basic familiar with data managing on MATLAB you need to know the special arithmetic operator in the MATLAB. They are +, -, *, / and .

Data handling: Now we will go to MATLAB and see how to manage data with using that type of arithmetic operator.

Run MATLAB, and open editor window by clicking New Script.

*** Type the following codes for use arithmetic operator (+):

`clc;`

`clear all;`

`a = 1;`

`b = 2;`

`c = (a+b);`

`disp(c);`

After type your codes click the Run tool, than the code will be simulate and its output will be showing on command window. See below the output screenshot.

Here I use clc for clear command window, and use clear all for clear all variable memory. Then I use variable a for store 1 and use variable b for store 2 and use variable c for store a+b. After I use function disp() for show output of the c, that mean a+b.

*** Type the following codes for use arithmetic operator (-):

`clc;`

`clear all;`

`a = 1;`

`b = 2;`

`c = (b-a);`

`disp(c);`

After type your codes click the Run tool, than the code will be simulate and its output will be showing on command window. See below the output screenshot.

Here I use same method of previews code. I just change here the arithmetic operator + to -. And (b-a). That mean I want to do subtract between b and a.

*** Type the following codes for use arithmetic operator (*):

`clc;`

`clear all;`

`a = 6;`

`b = 2;`

`c = (b*a);`

`disp(c);`

After type your codes click the Run tool, than the code will be simulate and its output will be showing on command window. See below the output screenshot.

Here I also use same method of previews code. I just change here the arithmetic operator – to *, variable’s a value 1 to 6 and (b*a). That mean I want to do multiply between ‘b’ and ‘a’ or ‘a’ and ‘b’.

*** Type the following codes for use arithmetic operator (/):

`clc;`

`clear all;`

`a = 6;`

`b = 2;`

`c = (a/b);`

`disp(c);`

After type your codes click the Run tool, than the code will be simulate and its output will be showing on command window. See below the output screenshot.

Now I hope you are able to understood the above code for use arithmetic operator ‘/’. If you understood the code for ‘+’, ‘-‘ and ‘*’ arithmetic operator so you may understood it.

Now please try with arithmetic operator ‘’ by typing codes yourself.
