SOME BASIC PROGRAMMINGS

Like C language you can write some basic programs using MATLAB  which is as simple as writing programs in C.

Here I discuss some basic programs to create an idea,  how we are going to write a program in MATLAB incoming future.

Program 1

WAP to print Hello World.

1. clc; %for clear screen
2. close all; %for closing all windows
3. clear all; %for clearing workspace
4. disp=input('Hello world');

Program 2

WAP to show the basic arithmetic operations.

1. clc; %for clear screen
2. close all; %for closing all winndows
3. clear all; %for clearing workspace
4. a=input('enter a number');
5. fprintf('a=%f\n',a);
6. b=input('enter another number');
7. fprintf('b=%f\n',b);
8. c=a+b;
9. d=a-b;
10. e=a*b;
11. f=a/b;
12. fprintf('sum of a and b = ');
13. fprintf('%f\n',c);
14. fprintf('difference of a and b = ');
15. fprintf('%f\n',d);
16. fprintf('multiplication of a and b = ');
17. fprintf('%f\n',e);
18. fprintf('division of a and b = ');
19. fprintf('%f\n',f);

Program 3

The distance of between two cities (in km) is input through the keyboard.  WAP to convert the distance of the city in meters, feet, inches, cm.

1. clc;
2. close all;
3. clear all;
4. dist=input('the distance between two cities in kms');
5. mtr= dist*1000;
6. fprintf('distance in meters=%d\n',mtr);
7. fet= dist*3280.83;
8. fprintf('distance in feet=%d\n',fet);
9. inch=dist*39370.07;
10. fprintf('distance in inch=%d\n',inch);
11. cms=dist*100000;
12. fprintf('distance in cms=%d\n',cms);

Program 4

WAP to find the simple interest of a principal amount given through keyboard.

1. clc;
2. close all;
3. clear all;
4. p=input('the principal amount is =');
5. fprintf('p=%f\n',p);
6. t=input('the time period is =');
7. fprintf('t=%f\n',t);
8. r=input('the rate of intrest is =');
9. fprintf('r=%f\n',r);
10. si= (p*t*r)/100;
11. fprintf('the simple intest is = %f',si);

Program 5

WAP to convert the temperature from Centigrade to Fahrenheit vice versa

1. clc;
2. close all;
3. clear all;
4. C1= input('the temp in Centigade = ');
5. F1= (C1*9/5)+32;
6. fprintf('the temp in Fahrenheit = %f',F1);
7. F2= input('\nthe temp in Fahrenheit = ');
8. C2 = (F2-32)*5/9;
9. fprintf('the temp in Centigrade = %f',C2);

Program 6

WAP to find the parimeter and area of  a rectangle through keybord input.

1. clc;
2. close all;
3. clear all;
4. l=input('the length of the rectangle = ');
5. b=input('\nthe breadth of the rectangle = ');
6. P=2*(l+b);
7. fprintf('\nthe perimeter of the rectangle  = %f',P);
8. A=(l*b);
9. fprintf('\nthe area of the rectangle  = %f',A);

Program 7

WAP to find the parimeter and area of  a circle through keybord input.

1. clc;
2. close all;
3. clear all;
4. r=input('the length of the radius of the circle = ');
5. P=2*pi*r;
6. fprintf('\nthe perimeter of the circle = %f',P);
7. A=pi*r^2;
8. fprintf('\nthe area of the circle = %f',A);

IF YOU HAVING ANY DOUBTS REGARDING THESE PROGRAMS, JUST LET ME KNOW BY YOUR COMMENTS OR  YOU CAN ALSO ASK ME IN  THE COMMENT BOX OR THROUGH EMAIL.

I WILL TRY TO SOLVE YOUR PROBLEMS AS SOON AS POSSIBLE.
