To determine the default variable that MATLAB differentiates with respect to, use symvar: symvar (f, 1) ans = t. Calculate the second derivative of f with respect to t: diff (f, t, 2) This command returns. ans = -s^2*sin (s*t) Note that diff (f, 2) returns the same answer because t is the default variable.

Matlab ought to be able to do this as you have it written, but I think that it doesn't like taking derivatives with respect to a symfun .

Df = diff (f,var) differentiates f with respect to the differentiation parameter var. var can be a symbolic scalar variable, such as x, a symbolic function, such as f (x), or a derivative function, such as diff (f (t),t). example Df = diff (f,var,n) computes the n …

The diff command then calculates the partial derivative of the expression with respect to that variable. For example, given the symbolic expression syms s t f = sin (s*t); the command diff (f,t) calculates the partial derivative ∂ f / ∂ t. The result is ans = s*cos (s*t) To differentiate f with respect to the variable s , enter diff (f,s)

12.11.2012 · A partial derivative can also be performed in Matlab. A partial derivative is defined as a derivative of a multivariable function with respect to one variable, with all other variables treated as constants. Let’s generate a new equation based on x, y, and z: g (x,y,z) = x*y^2 – sin (z).

Jun 24, 2016 · Let's define function x(t), its time derivative xdot(t), and expression T that is dependent on them: syms t x(t) xdot(t) = diff(x,t); T = (xdot + x)^2; We can all agree that partial derivative of T with respect to x is ∂T/∂x = 2*(xdot+x). However, if I do this in Matlab I get wrong answer:

11.11.2014 · I have no idea why this post has been put on hold. I'm aware of diff for symbolic derivative but not the problem I've stated. The problem is that some variables are depending on time so it is not straightforward to how to solve it. I've read Matlab's documentation but there is no an example provided regarding this matter. –
