How do you display a value on a MATLAB plot?

Direct link to this answer
  1. You can use text() or you can use annotate() . I would suggest that text() is much easier to use for this purpose.
  2. You could also build the value into the title() of the plot, of course.
  3. Your output appears to be a vector, so it is not immediately clear what output you want to display.
