Write a program to assign the following expressions to a variable A and then to print out
the value of A.
Code:
clc;
clear all;
% program for 1.a
a=3+4;
b=5+6;
z=a/b
% program for 1.b
% value of 2*pi*pi
disp('value of 2*pi*pi is=')
w=2*pi*pi
% program for 1.c
% value of square root 2
disp('value of square root 2=')
q=sqrt(2)
% program for 1.d
A=0.0000123;
B=5.67;
C=10^-3;
D=0.4567;
E=10^-4;
Z=(A+B*C)*D*E
Output:
z = 0.6364
value of 2*pi*pi is=
w = 19.739
value of square root 2=
q = 1.4142

Celsius temperatures can be converted to Fahrenheit by multiplying by 9, dividing by 5,
and adding 32. Assign a variable called C the value 37, and implement this formula to
assign a variable F the Fahrenheit equivalent of 37 Celsius.
Code:
T=input('Enter the temperature in degree celcius=')
c2=T;
f2=((c2*9)/5)+32;
disp('The temperature in Farhenite=')
disp(f2)
Output:
octave:1>
source("my_script.m")
Enter the temperature in degree celcius=
>
23
T = 23
The temperature in Farhenite=
73.400

Set up a vector called N with five elements having the values: 1, 2, 3, 4, 5. Using N,
create assignment statements for a vector X which will result in X having these values:
Code:
clc;
N=[1 2 3 4 5];
X=2*N;
disp(X);
X=N/2;
disp(X);
X=N.^-1;
disp(X);
X=N.^-2;
disp(X);
Output:
2 4 6 8 10 0.5000 1.0000 1.5000 2.0000 2.5000 1.0000 0.5000
0.3333 0.2500 0.2000 1.000000 0.250000 0.111111 0.062500
0.040000
