Question

Needs to be solved in MATLAB

Problem 4 Produce a conversion table for Celsius and Fahrenheit temperatures. The input to the function should be two numbers: Tlower and Tupper Which define the lower and upper range, in Fahrenheit, for the table The output of the function should be a two column matrix with the first column showing the temperature in Fahrenheit, from Tlower (32 °F) to Tupper (212 °F) with an increment of 5 °F, and the second column showing the corresponding temperature in Celsius NOTE: Conversion between Celsius and Fahrenheit is as follows: 5/9 (Fahrenheit Celsius 32) = Q13. What is temperature in Celsius for 57 °F? Q14. What is temperature in Celsius for 107 °F? Q15. What is temperature in Celsius for 192 °F?

Answer 1

a) Function file

function [T C]=fahrenheit2celcius(Tlower,Tupper)
Fahrenheit=Tlower:5:Tupper;
Celcius=(5/9).*(Fahrenheit-32);
T=Fahrenheit';
C=Celcius';
end

b) Script file

clc;clear all;
Tlower=32; %lower limit in degree Fahrenheit
Tupper=212;%upper limit in degree Fahrenheit
fprintf('Fahrenheit     Celcius');
[T C]=fahrenheit2celcius(Tlower,Tupper);
ans=[T C]
k=find(T==57);
fprintf('Temperature in Celcius for 57 def F= %f\n',C(k))

k1=find(T==107);
fprintf('Temperature in Celcius for 57 def F= %f\n',C(k1))

k2=find(T==192);
fprintf('Temperature in Celcius for 57 def F= %f\n',C(k2))
