Display matrix and string

Hi,

I want to display something like this:

            1 2 3             1
  x'(t) =   4 5 6   * x(t) +  2  * u(t)
            7 8 9             3

   y(t) =  [0 0 1] * x'(t)

The matrix and the vector are variable. Is it possible to display it with the disp()-function?

In additon it would be very nice if there is an opportunity to make an underline and a dot over a letter.

Thanks :)

You have to build the whole thing up using string manipulation. You would probably find that easiest to do using sprintf(). For the matrix part you might find it easiest to use num2str() as that automatically handles adjusting the spacing to get nice aligned columns.

thanks!!

do you know something about the underline and the dot ?

Put them on the line above or the line below.

You could also experiment with Unicode Combining Dot Above and Unicode Continuous Underline or Unicode Combining Low Line

If you use those then when you create your strings, remember to take into account that these will not add visual width but will take up length().
