 for i=0.01:0.1:1
    x=0:i:5; % create Vector of x 0 -> L
    N=length(x); % Calculate number of psi values (X)
    n=1:N; % Create Vector for n with length of N
    Vx=zeros([1 N]); % Create Vector of V(x)
    eval(['n(' num2str(i) '=n;']);
    % Calculate Energy & Potential
    [H,U,E] = CalcUandE(N,x,Vx,hbar,m);
    eval(['Hdx' num2str(i) '=H;']);
    eval(['Udx' num2str(i) '=U;']);
    eval(['Edx' num2str(i) '=E;']);
    % Find Analytic for E
    [Ea] = AnalyticE(hbar,n,m,L);
    eval(['Eadx' num2str(i) '=Ea;']);

Hi I am trying to run my above code and using it store the different values of n, Hdx, Udx, Edx however I am running into an error as my vector i for the loop has decimals. I am hoping some one can assist. Thanking you in advance :)

Use an index counter

counter = 1;
for step = 0.01 : 0.1 : 1
  % Loop code
  Hdx(counter) = % whatever.
  counter = counter + 1;
end

Don't use i as a loop index - it's also the imaginary variable. That's why I used step as the name of the loop index. Once you use an index for Hdx you won't need to use eval. See the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_create_variables_A1.2C_A2.2C....2CA10_in_a_loop.3F
