I got a task From my group studying class the Question is Quite confusing and I'm New to matlab. Here Is my Question and Plz Help me guys.

Write a Matlab script that, given the capacity of each room in the building and the size of a class, will attempt to find satisfactory room assignment that will accommodate the class in the building. If the class cannot be satisfactory placed, the script should print a “Room is not available” message, otherwise, a message saying that “Room number XX which has YY seats, is best for the class of size ZZ”.

An array indexed from 1 to 10 should be convenient structure for representing the capacities of each room in the building. The indices of the array element represent the room number as pictured below

To find a satisfactory room assignment (Best fit room number for a given class size), the number of leftover –remaining- seats for the room when the assignment is made should be minimum, where the (leftover seats) = (room capacity) - (class size).

If you post what you've done to try to solve this problem and ask a specific question you may receive some suggestions about how to move forward.

[Iddo Weiner]

pls provide some more details (and perhaps an example) - you need to write a function where the input data is class sizes and room sizes and the output is which class should be in which room?

Sir here is the sample run and thanks in advance

[Abdulrehman Khan]

here is some more info for the function

Here's a start. I trust you can finish it:

numClasses = 10;
roomCapacities = sort(randi(200, 1, numClasses), 'descend') % Sample data.
classSizes = sort(randi(200, 1, numClasses), 'descend')
classroomOccupied = false(1, numClasses)
for k = 1 : numClasses
  for c = 1 : numClasses
    if classSizes(k) < roomCapacities(c) && ~classroomOccupied(c)
      % Code for you to finish....
    end
  end
end

This is only one way of many, I'm sure.

[Abdulrehman Khan]

Thank You sir but you used loop and use of loop is not permitted

[Image Analyst]

Well, you should have given all that extra info before you first posted and I worked up this solution. What you need to do is to subtract the class size from the room capacities to determine if there are any zero or positive values, meaning empty seats.

emptySeats = roomCapacities - classSize;
emptySeats(emptySeats < 0) = inf;
[minValue, index] = min(emptySeats);

Try starting with/using that.

[Abdulrehman Khan]

Thank You sir but we advise not to use loop

[Image Analyst]

Where in the last 3 lines of the code I posted for you do you see a loop? Here they are again:

emptySeats = roomCapacities - classSize;
emptySeats(emptySeats < 0) = inf;
[minValue, index] = min(emptySeats);

There is no loop there. Which line has a "for" or "while" word on it?

[Andrei Bobrov]

r = [12 23 44 54 23 6 65 100 212 45]
c = [70,6,23,200]'

[a,b] = sort(r(:))
[ii,~] = find(cumsum((a(:) - c(:)') >= 0) == 1)
out = [b(ii),a(ii),c(:)]

[Abdulrehman Khan]

Sir how can I use this code

Answer 3

[Abu Yamen]

we should not use loop in this q only we can use find function and size then fprintf

[Walter Roberson]

It says that you cannot use loops but where does it say that you must use find()? There is a perfectly good solution with sort and interp1
