Is there someone here who is famular with Newton Raphson Method of solving nonlinear equations. According to a vacationing programmer it is supposed to help me write a program in C++ or VB to compute W(Z) i.e(compute x in Y=x*(e^x) when y is given). Does somebody know this stuff??
Thanks,
Dan

This is the Lambert W function. For a general reference see the Wikipedia
artice, and for something more specific on computing it see this artice.
