I have this:
VG = Table[i, {i, -30, 30, 0.1}]
VG - (Vch +A* (-PolyLog[2, -E^-BVch] + PolyLog[2, -E^BVch]) ) == 0
A and B are constants. I'm trying to solve for Vch (another table). Any suggestions?
thanks.
Are you trying to solve for exact values, or get a best fit in terms of least squares? It looks like the latter since there are so many points. I'd suggest checking FindFit if that is in fact the case.
