Hello, im new in MATLAB, and here's my problem: the while loop should be run at sometime, while each loop should take the if statement sequentially (while loop do work> take if statement>second loop>take elseif > 3rd loop> take else> 4th loop> if statement> and so on) i kinda new to use some of the feature like rem feature. Could you give me some guidance? thanks :)

i=1
a(i)=0
while true
    i = i+1
    a(i) = a(i-1) +1
    if a==1:3:15 
        disp('its first num')
    elseif a== 2:3:15
        disp('its sec num')
    else a==3:3:15
        disp('its 3rd num')s
    end
    if a > 20
        break
    end
end

Like this?

i=0;
while i <= 20
    i = i+1;
    r = rem(i,3);
    if r == 1
        disp('its first num')
    elseif r == 2
        disp('its sec num')
    else
        disp('its 3rd num')
    end
end
its first num
