You can display a matrix as an image with imshow

imshow(yourMatrix, []);

H needs to be a matrix - actual numbers - not a symbolic variable. I don't have the symbolic Toolbox. Is there anything in there that can make H into a matrix?

Are you trying to display a symbolic matrix in a text box in a figure window? Try something like:

syms a b c x
eq = a*x.^2+b*x+c == 0
S = solve(eq, x)
t = text(0.25, 0.75, ['$$' latex(S) '$$'], 'Interpreter', 'LaTeX')
t.FontSize = 30

Alternately, try writing those first three commands in a Live Script. The output is formatted in much the same way as the text object with the LaTeX interpreter is formatted. See this example for a sample of how symbolic expressions are formatted in a Live Script.
