Html code used along with Matlab

I have recently found that Matlab can use LaTeX character sequences. However, they only can be used by the functions text, title, xlabel, ylabel and zlabel. I have designed a GUI in which has an uitable. Its header is a string that uses HTML code and looks like this:
header = {'<center>Component X<br />(km/s^2)</center>', ...
'<center>Component Y<br />(km/s^2)</center>', ...
'<center>Component Z<br />(km/s^2)</center>'};
My intention is replacing s^2 with s squared. Because of I can not use LaTeX characters inside the string "header" (at least I had tried it and it did not work), I would like to know how I could do it if I use HTML code which I do not know.

Another approach:
header = {'<center>Component X<br />(km/s&sup2;)</center>', ...
'<center>Component Y<br />(km/s&sup2;)</center>', ...
'<center>Component Z<br />(km/s&sup2;)</center>'};
Well, the display of the HTML characters in this forum drives my crazy. Th "²" is written as "& s u p 2 ;" without the spaces.

header = {'<center>Component X<br>(km/s<sup><font size="-1">2</font></sup>)</center>', ...
'<center>Component Y<br />(km/s<sup><font size="-1">2</font></sup>)</center>', ...
'<center>Component Z<br />(km/s<sup><font size="-1">2</font></sup>)</center>'};
Note: you can leave off the </html> tags in practice.

@Walter Roberson: Thank you for your answer. I do not understand what your note means.

My note means that the following will also function:
header = {'<html><center>Component X<br>(km/s<sup><font size="-1">2</font></sup>)</center>', ...
'<html><center>Component Y<br />(km/s<sup><font size="-1">2</font></sup>)</center>', ...
'<html><center>Component Z<br />(km/s<sup><font size="-1">2</font></sup>)</center>'};

@Walter Roberson: I have proved your code but the command
<font size="-1">2</font>
has not effect on the superindex size (if I delete this part of the code, I get the same result). However, if I use the code given by Jan Simon, it does works. Can anybody explain me why?

The implemented HTML is not the full set of HTML and it is often difficult to predict what will work and what will not.
Jan's version works by inserting a particular character that is specifically a raised 2; my version (if it worked) would be the general HTML mechanism to raise text with a lower size.

@Walter Roberson: Thank you for your explanation. However, if both codes are HTML's ones, they should work correctly, independently of its general or particular character (I do not understand nothing. It should be matters of computing).
