Comme posso generare i risultati come hyperlink?

Cerco di execute questo su matlab online però alla fine, il TEX e PDF non sono scaricabili. Come posso farlo che si possono scaricare via matlab online?

% Define symbolic variables
syms A B C t

% Define the matrix ρ(t)
rho_t = [0, (1/8)*(1i - 3*sqrt(7))*A*exp(-t/2), (1/8)*(1i + 3*sqrt(7))*A*exp(-t/2); ...
    B*exp(-(3/4)*1i*(sqrt(7) - 1i)*t), -B*exp(-(3/4)*1i*(sqrt(7) - 1i)*t), -B*exp(-(3/4)*1i*(sqrt(7) - 1i)*t); ...
    C*exp((3/4)*1i*(sqrt(7) + 1i)*t), C*exp((3/4)*1i*(sqrt(7) + 1i)*t), C*exp((3/4)*1i*(sqrt(7) + 1i)*t)];

% Simplify the matrix
rho_t = simplify(rho_t, 'Steps', 50);

% Compute eigenvalues and eigenvectors symbolically
tic
[D, P] = eig(rho_t);
D = diag(D); % Extract diagonal eigenvalues
P = simplify(P, 'Steps', 50); % Simplify eigenvectors
P_inv = inv(P);
P_inv = simplify(P_inv, 'Steps', 50);
toc

% Display results
disp('Eigenvalues (D):');
disp(D);
disp('Eigenvector matrix (P):');
disp(P);
disp('Inverse of P (P^-1):');
disp(P_inv);

% Export to LaTeX
latex_rho = latex(rho_t);
latex_D = latex(diag(D));
latex_P = latex(P);
latex_P_inv = latex(P_inv);

% Write to a .tex file
fid = fopen('diagonalization.tex', 'w');
fprintf(fid, '\\documentclass{article}\n\\usepackage{amsmath}\n\\begin{document}\n\n');
fprintf(fid, 'The matrix $\\rho(t)$ is:\n\\begin{equation}\n\\rho(t) = \\begin{pmatrix}\n%s\n\\end{pmatrix}\n\\end{equation}\n\n', latex_rho);

What do you mean 'they are not downloadable'? Do you get an error when you download them? Or do you not see how to download them?

To download, find the file in your current folder browser, right-click on it, and select download.

Another option is to install MATLAB Drive Connector. This will automatically sync the contents of your MATLAB Drive to a local folder.

Note that your pdf is saving a blank image. You need to change the exportGraphics 'ContentType' option to 'image' for the text annotations to appear. Basically, the lines are too thin to be captured using the 'vector' option.
