WebNov 12, 2012 · The derivative of our function f (x) is equal to cos (x). To evaluate this derivative, or slope of f (x), at a certain value on the curve, we can use the function ‘subs’. For example to evaluate f' (pi): >> subs (deriv_f,pi) ans = -1. A partial derivative can also be performed in Matlab. A partial derivative is defined as a derivative of a ... Webcalculates the partial derivative ∂ f / ∂ t.
