yes, use "string" to convert a scalar variable to a string, see example 
below :

n=2; x=[-2:0.02:2]';y=x.^n;plot2d(x,y,5);
xtitle('$ y=x^{'+string(n)+'}$'), xstring(-0.5,1,'$x^{'+string(n)+'}=0$')

remark that the string send to "xtitle" or "xstring" must beging by "$" 
and end with "$"  (or "$$") otherwise latex code is not interpreted ...
