I have writtern this code to ask user to input number of rooms(x) (integer),room area (area(i)) (integer) and room type (string) and based on these selections, Q_env is calculated
This the code
to=input('Enter outside temperature: ');
ti=input('Enter inside temperature: ');
x=input('No of room: ');
for i=1:x
fprintf('ROOM %4.0f:', i)
area(i)=input('Area in meter square = ');
rt=input('Room type: ','s');
end
if rt=="external"
u1=0.6993;
dt=abs(to-ti);
Q_env=u1*area*dt
else if rt=="internal"
u2=1.3858;
dt=abs(to-ti);
Q_env=u2*area*dt
end
end
The following results are displayed when I run the previous code
Enter outside temperature: 40
Enter inside temperature: 20
No of room: 2
ROOM 1:Area in meter square = 20
Room type: internal
ROOM 2:Area in meter square = 30
Room type: external
Q_env =
279.7200
419.5800
419.5800
There are two problems here:
  1. rt only saves the last user input and I need all the room types corresponding to each room area to be saved to an array.
  1. Q_env is diplayed for the given number of rooms and the last result is repeated.
How can I overcome these two issues?

You have solved storing the set of areas using: area(i) . To store the set of CHAR vectors in a cell array, use: rt{i} .
If you do not want to display the resulat of a command, append a semicolon:
Q_env = u1 * area * dt;
% ^
