Index in position 1 exceeds array bounds. Erroy when trying to plot rectangle.

Hi, I'm trying to plot a rectangle given a corner coordinate and then 2 dimensions. I can get it working for one set of coordinates and dimensions in a array but no more than that when I input into my code that I have more than one room.

Here is the error code I get: Index in position 1 exceeds array bounds. Index must not exceed 1.

Does somebody know how to fix this. In my code the user inputs a given number of floors, rooms and dimensions (in addition to the style of the room but this doesn't affect this section). See my code below:

Thanks in advance for any help :)

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);
floorHeight=zeros(1,numberFloors);

    for i=1:1:numberFloors
        floorLength(i)=input(['Please enter floor ',num2str(i),' length: ']);
        floorWidth(i)=input(['Please enter floor ',num2str(i),' width: ']);
        floorHeight(i)=input(['Please enter floor ',num2str(i),' height: ']);
        numberRooms(i)=input(['Please enter the number of rooms on floor ',num2str(i),': ']);
    
        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 
        end

            for j=1:1:(numberRooms(i))
            roomLength(i,j)=input(['Please enter room ',num2str(j),' length: ']);
            roomWidth(i,j)=input(['Please enter room ',num2str(j),' width: ']);
            roomHeight(i,j)=input(['Please enter room ',num2str(j),' height: ']);

                if roomLength(i,j)<=0 || roomWidth(i,j)<=0 || roomHeight(i,j)<=0
                    disp('Room dimensions must be greater than 0');
                    return
                end
                list={'Residential','Office','Education','Toilet','Storage'};
                [indx,tf]=listdlg('ListString',list,'PromptString','Style of Room');
                roomType(i,j)=indx;
                answer = inputdlg({'X Coordinate','Y Coordinate'},'Room Coordinates',[1 50]);
                coordinatesX(i,j) = str2num(answer{1});
                coordinatesY(i,j) = str2num(answer{2});
            end
        n = numberRooms(1,1);
        for i = 1:1:n
            rectangle('Position',[coordinatesX(numberRooms,i) coordinatesY(numberRooms,i) roomWidth(numberRooms,i) roomLength(numberRooms,i)])
        end
    end

I don't know why you decided to suddenly abandon your indexing scheme. Replace all this:

n = numberRooms(1,1);
for i = 1:1:n
    rectangle('Position',[coordinatesX(numberRooms,i) coordinatesY(numberRooms,i) roomWidth(numberRooms,i) roomLength(numberRooms,i)])
end

With this.

for j=1:1:(numberRooms(i))
    rectangle('Position',[coordinatesX(i,j) coordinatesY(i,j) roomWidth(i,j) roomLength(i,j)])
    hold on
end

Thanks so much for the answer this sorted the problem. Do you know how to adjust the rectangle function so when it runs through the data it can change which axis it is plotting onto.

In my code it creates a new row for each of the floors which contains the rooms data. Is it possible to get my for loop to make an entirely new graph each time it uses data from a new row?

I hope this makes sense.

Thanks

If you call figure() in the outer loop prior to the loop that does the plotting, then it should create a new figure for each floor.

@DGM thank you
