I found this code, but the values are not writtes as in a matrix, but more link in a txt file.

  MGF =

    -3     7     2    -3
    10    12    12    12
     7     4    10    10
    12    12    10    12
     0    -3     2    -3
     7    10     7    10

Use the correct tool: uitable

Or you might be able to change the typeface (font) to a monospaced one.

Your MGF isn't a matrix. Encompass it with [] and ; for row separation and it should work. See the example below:

m = randi(5,6)
msgbox(num2str(m))

thanks for your answer.

But when i do is you write is the result as on the picture, and then it again looks like something that could be from a .txt file. Do you know how to fix this?

I don't think it's possible to have the matrix values perfectly aligned in the message box. But if you think about it, message box is a 'Figure' object. So instead of using 'msgbox', plot your data with i.e. heatmap and remove all of the formatting and you'll achieve the same result.
