How to create a Matlab symbol composition ∆t?

I'd like to create a single symbol which is contains a delta "∆" and a t. For visualisation purposes i use Matlab Live Script.

Combining several latin letters is easy done by:

sym('dt')

dt2

But these either result in an exception or don't do a conversion:

sym('Delta t')
sym('Deltat')

The workaround to multiply two symbols does not work in all cases:

sym('Delta')*sym('t')

deltat

(sym('Delta')*sym('t'))^2

delta2t2

However, if i square the symbol, i'd like to have this behavior:

sym('dt')^2

dt2

But it should contain the delta symbol:

deltat2

Is this what you want?

title('\Deltat')

If you want, you can also do

title('\Deltat^{2}')

The answer is no, you cant use non-ASCII for variables in MATLAB. This means no \Delta, no \epsilon, or any other non-standard chars.

You can generate the LaTeX representation of the results, and then print them either in text in MATLAB or in your favourite LaTeX editor with the function latex
