Question

MATLAB EXPERT PLS HELP!!! SHORT AND SIMPLE QUESTIONS!

Just write the code to do the following operations step by step please. You dont need background info on the question

1. Prompt the user to enter x and if x is less than 2 or not an integer, use a while loop to display “Invalid!” and prompt the user to re-enter valid entries.
2. Prompt the user to enter y as a vector of x elements. If the user did not enter in a vector containing at least 3 elements, use a while loop to display “Invalid!” and prompt the user to re-enter a valid vector
3. Print a menu showing options: 1 for temperature, 2 for heat flux, 3 for insulated, and 4 for convective.
4. Prompt the user to enter N as an integer number 1,2,3 or 4 and if the user didn’t enter a valid entry us a while loop to display “Invalid!” and prompt the user to enter a valid entry.
5. Based on the chosen value for N, prompt the user to enter to enter the remaining information:

• Temperature
• Heat Flux
• Convective: heat transfer coefficient in W/m2K and the outside temperature in Celcius

6. Prompt the user to enter p as a number. If the user did not enter in a valid option, use a while loop to display “Invalid entry!” and prompt the user to re-enter a valid option.

Answer 1

x=input('Enter x value : ')

f=1
% to validate x
while f
if (x>2) & (floor(x)==x)
f=0
else
disp('Invalid ')
x=input('Enter x value : ')
end
end
  

% to validate y
f=1
y=input('Enter y as a vector of x elements : ')
while f
if length(y)>=3
f=0;
else
disp('Invalid ')
y=input('Enter y as a vector of x elements : ')
end
end

disp('1 for temperature')
disp('2 for heat flux')
disp('3 for insulated ')
disp(' 4 for convective')

N=input('Enter N as an integer number 1,2,3 or 4 ')


% to validate N
f=1;
while f
if N>=1 & N<=4
f=0;
else
disp('Invalid ')
N=input('Enter N as an integer number 1,2,3 or 4 : ')
end
end

f=1;

p=input(' enter p as a number : ')
  
% to validate p
while f
if isnumeric(p)
f=0;
else
disp('Invalid ')
p=input(' enter p as a number : ')
end
end
