I wanted to take a moment and thank you for this comment, now I feel that is nicer latex being able to be used as an "add on" in Matlab.

I miss the possibility to write

xlabel('$\displaystyle\frac{\text{W}}{\text{h}}$','interpreter','latex')

for example. But that is not possible it seems. Mathematical font is not wanted for "Watt per hour" for example.

The easy way:

xlabel('^{a}/_{b}')

The more difficult way requires you to call the 'latex' interpreter and use LaTeX commands. See the link for the LaTeX documentation.

An old topic, but I've got an improved answer.

Star Strider's answer will work but it will look a bit silly. But like they suggest, you could use LaTeX interpreter instead.

Using LaTeX interpreter, you could accomplish this by writing:

xlabel('$\frac{a}{b}$','Interpreter','latex')

\frac{a}{b} is a LaTeX syntax for fractions. It will write 'a' to the numerator and 'b' to denominator. '$' symbols at the beginning and the end are necessary to interpret the expression in LaTeX Math mode, that interprets \frac correctly.
