Your use of z as variable makes me suspect you are using Newton-Raphson for complex-valued functions of a complex variable. If so, the issue is what you mean by "plotting" the function! There are many possible representations. David Park's Cardano3 package makes possible a number of these representations. If, though, your variable is real, then are you asking not for a plot of the function itself, but rather the related plot showing the Newton-Raphson iterates? bjarke wrote: > Hi everyone. > > We working on newton-raphson methods in mathematica.
