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.
My answer does not give the ratio. It gives:
f(x+Δx) - f(x)
----------------
Δx
Wasn't this your question?

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

Ls and delk should have the same length.
