MATLAB: Differentiation of a vector wrt a vetor

differentiationvectors

Hiii Friends,

Suppose i have two vectors

Ls = (1.2:0.0001:3.0).*1e-6;
delk = (x:y:z)   %some vector

I would like to differentiate d(Ls)/d(delk).

How do i do it?

Advance thanks for the advice.

Pavan

Assuming Ls and delk are of the same size:

diff(Ls)./diff(delk)

syms x y
f = (x^4)*sin(x*y);
der = diff(f,x,y,y)
der =
- 6*x^5*sin(x*y) - x^6*y*cos(x*y)

x = (0:23).';
n = numel(x);
out = datestr([ones(n,1)*[2012 3 10] x zeros(n,2)],'HH:MM');
