Can anyone share a Derivative code with me?
(not the "diff" function) I need a code that will do derivative to a mathematical function that the user will enter.
I want to use the GUI menu, so the mathematical function will enter in that menu, and i will show the graph of the function and the derivative of the function. and later will enter also a value, to the function.
Thank you.

But the diff( ) function does this for you with symbolic inputs (you need the Symbolic Toolbox). E.g.,
>> syms x
>> f = 3*x^2 + 2*x + 1
f =
3*x^2 + 2*x + 1
>> diff(f)
ans =
6*x + 2
>> f = sin(x)^2
f =
sin(x)^2
>> diff(f)
ans =
2*cos(x)*sin(x)

yes,
but i need a way without using the "diff" function.
is there any possiable code to write that will do that?
is there any code for that anywhere that i can copy?
or maybe it is not much effort to do for some experienced matlab user?
just for simple mathematical function (polynomials)

All you'd have to do is write an output formatting line which is one
line of code if you're not wanting fancy, possible a few more to have
actual TeX formulae or the like...

Do not create a new thread when replying to a post. This makes it hard to follow the conversation. Instead, do a reply to the existing post.
