amssymb LaTeX symbols in plots

Good afternoon,

I'm often using LaTeX to annotate plots created in MATLAB, e.g. (this is obviously just a silly example)

plot(0:0.01:2*pi, sin(0:0.01:2*pi))

text(4, 0.8, '$X > 0$', 'Interpreter', 'latex')

This is fine --- until you need a symbol not provided by base (La)TeX but rather by a LaTeX package such as amssymb. For example,

text(4, 0.8, '$X \gtrless 0$', 'Interpreter', 'latex')

will not work and instead produce a warning ("String scalar or character vector must have valid interpreter syntax: $X \gtrless 0$").

Is there a way to use such symbols from within MATLAB? Alternately, is there some other way of producing the \gtrless symbol, specifically?

Thank you & keep the cheer,

Chris

The following documentation shows the list of supported Greek symbols and special characters (along with corresponding syntax):

Setting the Interpreter property 'latex' allows additional formatting.

Specifically, for '>=' latex symbol in a MATLAB plot.

Use:

plot(0:0.01:2*pi, sin(0:0.01:2*pi))
text(4, 0.8, '$X \geq 0$', 'Interpreter', 'latex')

Thanks for the link to the list of supported symbols, that's very helpful! Unfortunately \geq is not the one I'm looking for, however.
