MATLAB: Place down error underneath text string

annotation;arrowposition;text;

Hi all,

to place a down arrow for a text annotation in a plot I can use…

text(0.5,0.5,'\downarrow mytext')

..which puts the arrow to the left of the text or…

text(0.5,0.5,'mytext \downarrow')

which put the error to the right of the text.

What is the code for placing the down arrow underneath the text string?

Best Answer

'$\stackrel{mytext}{\downarrow}$'

with 'interpreter', 'latex'

MATLAB: How to make Greek characters and regular text have same font weight in Tex markup

Greek letters are displayed in a different font style, so we expect them to appear slightly different. However, here are several possible approaches to make the Greek characters and regular text appear more similar:

1) Use the LaTeX interpreter so that all items are displayed using the LaTeX font style:

This requires wrapping what must be interpreted as a formula into $$:

text( 0.5, 0.5, {'$\alpha$','name'}, 'Interpreter', 'latex' ) ;

2) Split up your call to "text", first displaying the Greek character as bold, then displaying the regular text as not bold. For example,

text( 0.5, 0.5, '\bf\alpha');

text( 0.5, 0.5, ' name');

The two pieces of text should now be more similar in font weight.

3) Another option to consider is changing the font style of the regular text such that it is more similar in weight to the Greek characters. You can do this by using the "\fontname{}" modifier
