how can I display an equation with the constants in the title

for example:

 title(['something something is' num2str(n=n1*e^(ax))])

Amruta - you can try using sprintf to create a string equation. Something like

 n  = 12;
 n1 = 13.3;
 ax = 42.42;
 ['something something is ' sprintf('%f=%f*e^(%f)',n,n1,ax)]

would produce the string

 something something is 12.000000=13.300000*e^(42.420000)

You can do a better job of the formatting if you know if n, n1 and ax are integers are floats and (if the latter) how many digits after the decimal you wish to display. See format specification for sprintf for more details.
