Question
Part 1. MATLAB Programming The wind chill factor measures how cold it feels with a given air temperature T (in degrees Fahrenheit) and wind speed (V, in miles per hour). The formula is approximately
WCF = 35.7 + 0.6T ? 35.7(V0.16) + 0.43T(V0.16)
a). Write a function that will calculate the wind chill factor (WCF) given temperature and wind speed. Your function should round down to the nearest integer.
b). Write a script that will use the function above to create a table of wind chill factors, similar to the one shown at https://en.wikipedia.org/wiki/Wind_chill#/media/File:Wind_chill.png. Wind speed should be down the left and temperature across the top.
Please show output if possible Thanks
Explanation / Answer
Code For Wind_Chill_Factor.m
%------------------------------------------
function [ Tw ] = Wind_Chill_Factor( Ta,v)
%UNTITLED8 Summary of this function goes here
% Detailed explanation goes here
Tw = round(35.74 + 0.6215*Ta - 35.75*v^0.16 + 0.4275*Ta*v^0.16);
end
%--------------------------------------------------
Code for main.m
%---------------------------------------------------------
clc;clear;
Ta = input('Enter the Temperature = ');
v = input(' Enter the Wind Velocity = ');
Tw = Wind_Chill_Factor( Ta,v);
sprintf('Wind Chill Factor Tw = %f',Tw)
%%
v = 5:5:60;
t = flip(-45:5:40);
T = ones(length(v)+1,length(t)+1);
T(1,1) = NaN;
% T(1,j) = t(j-1);
% T(i,1) = v(i-1);
for i = 2:(length(v)+1)
T(i,1) = v(i-1);
for j = 2:(length(t)+1)
T(1,j) = t(j-1);
T(i,j) = Wind_Chill_Factor( t(j-1),v(i-1));
end
end
T

Enter the Temperature = 50
Enter the Wind Velocity = 20
