Complicated matlab for loop using user's input

Hello everybody,

So i ran into this problem, where i've got a number x=m:.1:m+4*pi and i have to create a for loop which would increase the m value by pi/8 every 0.5 seconds for 15 times and then graph it and I just have no idea how to make it work.. so far I have done this much:

%------
prompt='Iveskite skaiciu m: ';
m=input(prompt);
x=m:.1:m+4*pi;
prompt2='Pasirinkite funkcija cos(B)/sin(A): ';
f=input(prompt2,'s');
if strcmp(f,'A')
    fun=@sin;
elseif strcmp(f,'B')
    fun=@cos;
else
    error('invalid selection')
end
figure(1),clf(1)
plot(x,fun(x))
%------

for a = 0:15
  for k = m:0.1:m<m+4*pi
       x(a,k) = m:.1:m+4*pi;
  end
end

It's not much, but I tried my best.

By the way, the number m is a user's input.

str2func() should play a role here just look into the doc

Could you give an example how and where would it play the role in my loop?
