Coin Flip simulation errors

Here's my function code

H=nest1;

T=nest1;

function [H,T]=nest1(n,k)

while n <= k

      n=n+1;

      R = randi([1,2]);

      H=0;

      T=0;

      if ISEQUAL(R,1)

          H=H+1

          disp('H')

      end

      if ISEQUAL(R,2)

          T=T+1

          disp('T')

      end

end

end

end

here's my main code:

clear all, close all, clc

prompt='How many times do you want to flip the coin?';

k=input(prompt)

[htotal, ttotal]=coinflip(k)

I keep receiving a Not enough input arguments error at my while loop. I'm trying to do a coin flip function by calling a function in my main. any tips? I really need the help.

Does the code in http://uk.mathworks.com/matlabcentral/answers/256701-coin-flip-plotting-every-flip imply that you solved this Question ?

In nest1.m, you cannot have these two lines before your function line:

H=nest1;
T=nest1;

See the FAQ: http://matlab.wikia.com/wiki/FAQ#How_do_I_fix_the_error_.22Function_definitions_are_not_permitted_in_this_context.22.3F

Also, your main code calls coinflip(), the code for which you did not post. You posted only code for next1().
