As of MATLAB 7.0 (R14), "LaTeX" has been added as an optional interpreter for text objects in a figure.

In order to put a hat on a character that is to be displayed within a figure, the "Interpreter" property of the text should to be set to "LaTeX" and the equivalent LaTeX command "\hat{x}" should be typed as "$$\hat{x}$$".

For example, to have "x-hat" displayed in the X-Label, do the following:

xlabel('$$\hat{x}$$','Interpreter','Latex')

Another example to have "x-hat" displayed as text is:

text(xp,yp,'$$\hat{x}$$','Interpreter','Latex')

where "xp" and "yp" determine the position of the displayed text.

There are no known workarounds for MATLAB 6.5.1 (R13SP1) or earlier versions.

As of MATLAB 7.0 (R14), "LaTeX" has been added as an optional interpreter for text objects in a figure.

In order to have an em-dash displayed within a figure, the "Interpreter" property of the text should to be set to "LaTeX" and the equivalent LaTeX command "\---" should be typed.

For example, to have "x-hat" displayed in the X-Label, do the following:

plot(1:10)
%An example to have "emdash" displayed as title is:
title(['This is an example for emdash' '---'],'Interpreter','Latex')
%Another example to have "emdash" displayed as text is:

MATLAB: How to add a hat on a character which is displayed in the LEGEND of a figure in MATLAB 7.0 (R14)

As of MATLAB 7.0 (R14), "LaTeX" has been added as an optional interpreter for text objects in a figure.

The legend of a figure is an axes object. The text object in the legend is a child of the parent axes object. The following code demonstrates how a 'hat' can be added with the LEGEND function:

% Plot a line
plot(1:10);
% Create a blank legend
h = legend('');
% hchild is the handle to the children of the axes object.
% In this case it is a 3 by 1 vector and hchild(3) is the
% handle to the string in the legend
hchild = get(h,'children');
% Set LaTeX as the interpreter
set(hchild(3),'Interpreter','LaTeX');
% Add x with a hat to the legend in the current figure
set(hchild(3),'String','$$\hat{x}$$');
