However you can create your transfer function with all symbols. s= sym (s) k = sym (k) H= (k*s+k)/ (s^2+s+1) Or you could assign some dummy value to k and then change it when your program needs. WebYou can differentiate symbolic functions, integrate or simplify them, substitute their arguments with values, and perform other mathematical operations. For example, find the derivative of f (x,y) with respect to x. The result dfx is also a symbolic function. dfx = diff (f,x) dfx (x,y) = 2*x*y. Calculate df (x,y) at x = y + 1.
