Differentiate function by a functionI'm just a little bit lost here. I'm using the latest MATLAB release with the symbolic maths toolbox. At the moment I'm working on a system, which has equations like x=theta(t)+2 (of course a lot more complicated and longer). Now I would like ...
(f,t) f = (x^2 - 2*x + 1)*(3*x^3 - 5*x^2 + 2) der3 = differentiate(f,x) f = (2*x^2 + 3*x)/(x^3 + 1) der4 = differentiate(f,x) f = (x^2 + 1)^17 der5 = differentiate(f,x) f = (t^3 + 3* t^2 + 5*t -9)^(-6) der6 = differentiate(f,t...
You can differentiate the Bessel function of the first kind,besselj(nu,z), with respect toz. Get symsnuzb = besselj(nu,z); Db = diff(b) Db = ν Jν(z)z−Jν+1(z) Thedifffunction can also take a symbolic matrix as its input. In this case, the differentiation is done eleme...
Hi to all. I have a piecewise function and I want to differentiate it but the derivative will not exist at endpoints. I tried to interpolate it such that the edges are more smooth and the derivative is continuous, but when I plot it, I still get the harsh edges. What to do now? Th...
Use polyder to differentiate the polynomial. The result is q(x)=15x4-6x2+1. q = polyder(p) q = 1×5 15 0 -6 0 1 Differentiate Product of Polynomials Create two vectors to represent the polynomials a(x)=x4-2x3+11 and b(x)=x2-10x+15. a = [1 -2 0 0 11]; b = [1 ...
You can differentiate symbolic functions, integrate or simplify an expression. The result is also a symbolic function. Differentiate, >> dfx = diff(f,x) dfx(x, y) = 2*x*y 1.5 Symbolic Matrices Use matrices containing symbolic values. ...
