hy,
i'll try to explain my problem.
i've a set of data (number)
those data will be inserted in a graph
i want to fit (interpolate) those data with a bi exponential( two term exponential) function.
there is a function like this in matlab but i must insert this function in excel to do a complete worksheet.
thanks
Luca
