WebIf you use nested diff calls and do not specify the differentiation variable, diff determines the differentiation variable for each call. For example, differentiate the expression x*y by calling the diff function twice. Df = diff (diff (x*y)) Df = 1. In the first call, diff differentiates x*y with respect to x, and returns y.

WebTo 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. 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 ...
