Programming in MATLAB for Beginners-4

Let's take some examples:

Create a vector of the even whole numbers between 45 & 98.:

to perform this operation use " : " operator

X=[46:2:98];

Compute the length of hypotenuse of a right triangle if the length of two other sides are given:

We can calculate the hypotenuse of a right triangle using this formula C²=A²+B²

A=input('enter the value of base ');

B=input('enter the value of perpendicular side ');

C=sqrt(A^2+B^2);

['length of hypotenuse']

disp(C)

Concatenation of two matrices:

Suppose we have two matrices A & B

we can conctenat both matrices as follow-

C=[A B];

or

C=[A ; B];

How to convert a number into a string:

use num2str(A) to perform above operation

consider previous example of right triangle once again

A=input('enter the value of base ');

B=input('enter the value of perpendicular side ');

C=sqrt(A^2+B^2);

disp(['length of hypotenuse ',num2str(C)])
