HELP NEEDED!

Hello physicsblr people of Tumblr! I'm having an issue with a MATLAB app file, and was wondering if anyone knew what the deal with it might be. Code + more info under the cut! Any help/commiseration/reblogs MUCH appreciated :)

Essentially, I'm looking to model a free particle wave packet dispersing over time. In the base code, it works just fine! See:

However, once I switch it into the app editor, attach the wavelength value to a slider, and change all the plot functions to be on the UIAxes, it will only plot the initial state. See:

If anyone knows why the code (below, "problem areas" highlighted in red) won't evolve over time in the app like it does in the code editor, PLEASE help!

APP CODE:

% Parameters, Constants and Other Such Sundry Items Nx = 501; % Number of x points [1001] Nt = 4000; % Number of time steps (not seconds) L = 5e-9; % Width of X domain [5e-9] me = 9.11e-31; % electron mass hbar = 1.06e-34; % Planck's constant e = 1.602e-19; % elementary charge x = linspace(0,L,Nx); dx = x(2) - x(1); C1 = 1/10; % Various Constants and things to make life easier dt = C1 * 2 * me * dx^2 / hbar; C2 = e*dt/hbar; % Functions, etc. psiR = zeros(Nt,Nx); % wave function—real part psiI = zeros(Nt,Nx); % wave function—imaginary part U = zeros(1,Nx); % potential energy

% Starting packet position nx1 = round(Nx/6); s = L/25; % wave pulse width wL = app.WavelengthSlider.Value; % this is the only modification to this part of the code. In the original code, it's set to 1.6e-10. yR = exp(-0.5.*((x-x(nx1))./s).^2).*cos((2*pi).*(x-x(nx1))./wL); yI = exp(-0.5.*((x-x(nx1))./s).^2).*sin((2*pi).*(x-x(nx1))./wL); psiR(1,:) = yR; psiI(1,:) = yI;

% Solve Schrödinger Equation

for nt = 1 : Nt-1 for nx = 2 : Nx - 1 yR(nx) = yR(nx) - C1*(yI(nx+1)-2*yI(nx)+yI(nx-1)) + C2*U(nx)*yI(nx); end psiR(nt+1,:) = yR; for nx = 2 : Nx-1 yI(nx) = yI(nx) + C1*(yR(nx+1)-2*yR(nx)+yR(nx-1)) - C2*U(nx)*yR(nx); end psiI(nt+1,:) = yI; end for nt = 2:Nt psiI(nt,:) = 0.5*(psiI(nt,:) + psiI(nt-1,:)); end % Plotting (This is where the troubles begin; app axes callbacks correspond to the above labelled axes)

for time = 1: 100: Nt

xP = x.*1e9; yP = psiR(time,:); plot(app.PsiRAxes,xP,yP,'Color','#54b0b6','linewidth',2) hold on yP = psiR(1,:); plot(app.PsiRAxes,xP,yP,'Color','#54b0b6','linewidth',1) hold off grid on box on xP = x.*1e9; yP = psiI(time,:); plot(app.PsiIAxes,xP,yP,'Color','#E1C699','linewidth',2) hold on yP = psiI(1,:); plot(app.PsiIAxes,xP,yP,'Color','#E1C699','linewidth',1) hold off grid on box on xP = x.*1e9; yP = psiR(time,:).^2 + psiI(time,:).^2; plot(app.ProbAxes,xP,yP,'k','linewidth',2) hold on yP = psiR(1,:).^2 +psiI(1,:).^2; plot(app.ProbAxes,xP,yP,'k','linewidth',1) hold off grid on box on hold off pause(0.1)

end
