Diff function in matlab

WebBecause the initial conditions contain the first- and second-order derivatives, create two symbolic functions, Du = diff (u,x) and D2u = diff (u,x,2), to specify the initial conditions. syms u (x) Du = diff (u,x); D2u = diff (u,x,2); Create the … WebMATLAB provides the diffcommand for computing symbolic derivatives. In its simplest form, you pass the function you want to differentiate to diff command as an argument. For example, let us compute the derivative of the function f(t) = 3t2+ 2t-2 Example Create a script file and type the following code into it − syms t f = 3*t^2 + 2*t^(-2); diff(f)

A way to go would be to decide an epsilon and use the Newton's difference quotient: epsilon = 1e-10; f = @(x) x^2+2*x+1; f1 = @(x) (f(x+epsilon) - f(x)) / epsilon; japanese fashion a cultural history https://houseoflavishcandleco.com
