Hi,
I have a very big data of voltage against time, and the data needs to fit a dynamic model. I am aware of how to do linear regression modelling using matrices, but i couldnt find any useful information about dynamic modelling. So can someone suggest how i go about doing this problem?
The model should fit the form,

R = R0 + R1[1-exp(-t/c1)] + R2[1-exp(-t/c2)]

and

R = R0 + R1exp(-t/c3) + R2exp(-t/c4)

Would martices be a possible way as well?
Thanks for your replies.
