MATLAB: Derivative of a Function

derivative function

Is there a way to input a function as "g=@(x) exp(x^2-2);" and take the derivative?

Best Answer

If you have the Symbolic Toolbox:

>> g = @(x) exp(x^2-2)
g = 
    @(x)exp(x^2-2)
>> syms x
>> diff(g(x))
ans =
2*x*exp(x^2 - 2)

Convert everthing to symbolic to prevent the loss of precision

syms x
e = exp(sym(1));
f = x * e^x^2; 
format short
df = diff(f)

Result

>> df
df =
exp(2*x) + 2*x*exp(2*x)

The heavside function is not the same as the sign function, you can't simply change one for another. If you want to write the sign function in terms of a heavside function you can use the following relation:

Where

is the heavside function.
