Creating small elevator code

I created a code for a random amount of people to get into the elevator and an exact same random of floors selected but I am having trouble setting up the ascending part. I tried to do the for/end function to automatically go but it came to an error, can someone help please.

%Elevator
a = nonzeros(round(10*rand(1,1))) %number of people entering                                                                                                                                                                                                                                                                                                                                                                                                                                                              
e(1).floor='lobby';
e(2).floor='firstfloor';
e(3).floor='secondfloor';
e(4).floor='thirdfloor';
e(5).floor='fourthfloor';
e(6).floor='fifthfloor';
e(7).floor='sixthfloor';
e(8).floor='seventhfloor';
e(9).floor='eightfloor';
e(10).floor='ninethfloor';
n = round(9*rand(1,a)) %number floor selected
o = n
for o = [1:10]
    x(o) = n*1;
end
%%I was going to try this but it seemed more messy
%if(num1>num2)
%    disp('num1 goes first')
%elseif (num1>num3)
%    disp('num1 goes first')
%elseif (num1>num4)
%    disp('num1 goes first')
%elseif (num1>num5)
%    disp('num1 goes first')
%elseif (num2>num1)
%    disp('num2 goes first')
%elseif (num2>num3)
%    disp('num2 goes first')
%elseif (num2>num4)
%    disp('num2 goes first')
%elseif (num2>num5)
%    disp('num2 goes first')
%elseif (num3>num1)
%    disp('num3 goes first')
%elseif (num3>num2)
%    disp('num3 goes first')
%elseif (num3>num4)
%    disp('num3 goes first')
%elseif (num3>num5)
%    disp('num3 goes first')
%elseif (num4>num1)
%    disp('num4 goes first')
%elseif (num4>num2)
%    disp('num4 goes first')
%elseif (num4>num3)
%    disp('num4 goes first')
%elseif (num4>num5)
%    disp('num4 goes first')
%elseif (num5>num1)
%    disp('num5 goes first')
%elseif (num5>num2)
%    disp('num5 goes first')
%elseif (num5>num3)
%    disp('num5 goes first')
%elseif (num5>num4)
%    disp('num5 goes first')
%else
%    disp('no floor is selected')
%end

Problem is you are trying to make an array (1xN) to fit into a single array (1x1). What exactly are you trying to do with this code?

n = round(9*rand(1,a)) %number floor selected
