Why can't matlab2tikz represent annotations, such as textarrow, on figures?

Programe:

close all; clear all; clc

x=1:100; y=sin(x);

figure(1);

plot(x,y);

axis([0 100 -5 5]);

annotation('textarrow',[0.2 0.5],[0.2 0.5],'string','Note');

matlab2tikz('graph.tikz', 'height', '\figureheight', 'width', '\figurewidth');

Problem:

Warning: Don't know class 'scribe.textarrow'. Default handling.

Thanks to all.

matlab2tikz is not a predefined function of MATLAB. Can you show the function itself to find the source of error within that function?

It's easier to send you the file with the functions. Thank you for your time.

It appears that you may be using http://www.mathworks.com/matlabcentral/fileexchange/22022-matlab2tikz

Questions about why it does or does not support something should be addressed to the author of the code. The File Exchange is code contributed by volunteers.
