To click the mouse several times

Question

If 4 'Filloval' appear, you must select all 4 ovals. If the same oval is selected 4 times, only 1 oval is selected, so the code should not terminate. However, my current code terminates when selecting the same oval four times.

We created a matrix, and if we click on one oval, we're going to erase the column that corresponds to one oval so that it doesn't end if we press one oval in duplicate.

The problem is that if you click one oval in the (14) matrix to create a (13) matrix, the (13) matrix must be maintained, but it does not.

for mouse = 1 : 4  % mouse 4 click
    
    ShowCursor (0); 
    SetMouse(xCenter, yCenter*1.9, windowPtr);   

    click = 1;
        
            while click == 1;

            [xMouse, yMouse, buttons] = GetMouse(windowPtr);

            inside1 = IsInRect(xMouse, yMouse, Tchoicecenter);
            inside2 = IsInRect(xMouse, yMouse, Tchoicecenter2);
            inside3 = IsInRect(xMouse, yMouse, Tchoicecenter3);
            inside4 = IsInRect(xMouse, yMouse, Tchoicecenter4);
            
            if inside1 == 1 
               Rectlocation(:,mouse) = Tchoicecenter;  
               if any(buttons)
                  break
               end
            elseif inside2 == 1
               Rectlocation(:,mouse) = Tchoicecenter2; 
               if any(buttons)
                  break
               end
            elseif inside3 == 1
               Rectlocation(:,mouse) = Tchoicecenter3; 
               if any(buttons)
                  break
               end
            elseif inside4 == 1
               Rectlocation(:,mouse) = Tchoicecenter4; 
               if any(buttons)
                  break
               end       
            end

            Tovalcenter = CenterRectOnPoint(ovalBaseRect, TXpos, TYpos);
            Tovalcenter2 = CenterRectOnPoint(ovalBaseRect, TXpos2, TYpos2);
            Tovalcenter3 = CenterRectOnPoint(ovalBaseRect, TXpos3, TYpos3);
            Tovalcenter4 = CenterRectOnPoint(ovalBaseRect, TXpos4, TYpos4);

            Screen('FillOval', windowPtr, TColor, Tovalcenter); 
            Screen('FillOval', windowPtr, TColor, Tovalcenter2); 
            Screen('FillOval', windowPtr, TColor, Tovalcenter3); 
            Screen('FillOval', windowPtr, TColor, Tovalcenter4); 
            end

   mouseans = [1:4 ; inside1 inside2 inside3 inside4];
       
   a = find(mouseans(2,:) == 1);     % mouse click (True == 1)
   mouseans(:,a) = []

end

My current result:

mouseans = 1 3 4         % 2 oval click
           0 0 0

mouseans = 1 2 3         % 4 oval click
           0 0 0

mouseans = 1 2 4         % 3 oval click
           0 0 0

mouseans = 2 3 4         % 1 oval click
           0 0 0

The desired result:

mouseans = 1 3 4         % 2 oval click
           0 0 0

mouseans = 1 3           % 4 oval click
           0 0 

mouseans = 1             % 3 oval click
           0 

mouseans = []            % 1 oval click
           

How can I click all four ovals without the program terminating?
