Hi all,
I want to find the slope of the tangent of the I-V graph (this is ploted from the raw data) at V=O and I=0. Can anyone help me to do this?. I don't have a good command on Matlab.
Thanks in advance.

I am not certain what you want.
See if the gradient funciton does what you want. It requires evenly-spaced data with known differences between the points, however you can get around that with:
dydx = gradient(y) ./ gradient(x);
That slope will probably be what you want.
If it is not, experiment!
