Differentiation of a vector wrt a vetor

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.

Assuming Ls and delk are of the same size:

diff(Ls)./diff(delk)

Hii Friend, sorry if my question is wrongly explained...

I would like to differentiate Ls wrt delk. It is not the ratio.

[Giorgos Papakonstantinou]

My answer does not give the ratio. It gives:

 f(x+Δx) - f(x)
----------------
       Δx

Wasn't this your question?

[Pavan Kumar]

Thank you..That was wanted i wanted. But when i try plotting i get error 'Vectors must be of same length'

[Andrew Newell]

Ls and delk should have the same length.

Thank you Andrew and Giorgos.
