 Author Comment/Response Peder 08/02/12 07:00am Hi, I have a complex function, whose real and imaginary parts I am trying to plot separately. I have manually plugged in some more or less random (relevant) values for the variable, so I know the function is defined on the range I'm looking at. That is, I do: N[Re[function[x]]] for some different x's (have also done Im[]) values of x (x is real). This works just fine. However, when I try to plot this function over the same range of x, the graph simply stops at one point, and doesn't plot the rest of the curve, although I know these points are perfectly well defined. Then I thought I could write a loop that forces it to evaluate exactly the points that I want, but the same thing happens. The loop looks like this: TMover5aIList = {}; min = 0.1 10^12; max = 1.6 10^12; steps = 0.1 10^12; delta = 0.01 10^12; For[i = min, i <= max, i += delta, TMover5aIList = Append[TMover5aIList, {i, N[Im[\[Beta]z[4750 - 169 I, i]]/((2 \[Pi] i) Sqrt[\[Epsilon]0 \[Mu]0])]}]; ] TM5aI = ListPlot[TMover5aIList, Joined -> True, PlotStyle -> {Purple, Dashed}]; Where beta_z is sqrt(linear_in_x - complex_constant) Do you know what's going on here? [I've attached a picture of the graph, showing where it stops (purple, dashed curve)] Attachment: GraphProblem.gif, URL: ,
