I'm sorry if I'm not formerly correct; I would like to work with symbolic functions, like i.e.
x(t) without the need to actually define
This may be useful because sometimes you'll have functions of
x, and you want to calculate the derivative in
t. For example
y(x) = y(x(t)) = t*x(t) d y(x) d x(t) ------ = x(t)+ t* ------ d t dt
Is there a way to accomplish this in matlab?
