Zeros error when entering matrix data

Hi, I'm new to MATLAB for university and have got stuck on a part of code with a zeros error. Perhaps I should be using something different to zeros?

I'm entering floor dimensions and then room dimensions with the long run intention to develop the code further to get MATLAB to generate a floorplan and 3D plan of the building.

If I enter input into my code that I want 1 floor with a given number of rooms and dimensions the code works fine. If I enter more than 1 floor and then room dimensions the code fails with the error:

"Error using zeros

Size inputs must be scalar.

Error in Coursework_TW_testfile

roomLength=zeros(1,numberRooms);"

Here is my code:

clear;

numberFloors=input('Please input the number of floors required: ');

if numberFloors<=0

disp('Number of floors must be at least 1');

return

else

disp('Thanks');

end

floorLength=zeros(1,numberFloors);

floorWidth=zeros(1,numberFloors);

mainlooptotal=1;

while mainlooptotal<=numberFloors

for i=1:1:numberFloors

floorLength(i)=input(['Please enter floor ',num2str(mainlooptotal),' length: ']);

floorWidth(i)=input(['Please enter floor ',num2str(mainlooptotal),' width: ']);

floorHeight(i)=input(['Please enter floor ',num2str(mainlooptotal),' height: ']);

numberRooms(i)=input(['Please enter the number of rooms on floor ',num2str(mainlooptotal),': ']);

if floorLength(i)<=0 || floorWidth(i)<=0 || floorHeight(i)<=0 || numberRooms(i)<=0

disp('Floor dimensions and number of rooms must be greater than 0');

return

else

mainlooptotal=mainlooptotal+1;

end

roomLength=zeros(1,numberRooms);

roomWidth=zeros(1,numberRooms);

roomlooptotal=1;

while roomlooptotal<=numberRooms

for j=1:1:numberRooms

roomLength(j)=input(['Please enter room ',num2str(roomlooptotal),' length: ']);

roomWidth(j)=input(['Please enter room ',num2str(roomlooptotal),' width: ']);

roomHeight(j)=input(['Please enter room ',num2str(roomlooptotal),' height: ']);

if roomLength(j)<=0 || roomWidth(j)<=0 || roomHeight(j)<=0

disp('Room dimensions must be greater than 0');

return

else

roomlooptotal=roomlooptotal+1;

end

end

end

end

end

Thank you in advance.

Answer 1

[VBBV]

roomLength=zeros(1,(numberRooms(i)));
roomWidth=zeros(1,(numberRooms(i)));

Give the size of numberRooms

[VBBV]

 for j=1:1:(numberRooms(i))

Thanks that's working now :)
