Hi. I'm trying to make a small animation of a 3D Sinc function with a phase element added: Sinc[0] := 1; Sinc[0.] := 1; Sinc[x_] := Sin[x]/x; sincmovie = Table[ Plot3D[ Sincphase[(x x+y y)^(1/2),time] , {x,-20,20}, {y,-20,20} , PlotPoints->80, PlotRange->{-0.5, 1}, Mesh->False] {time, 1, 1}]; A single frame using a fixed value for 'time' plots fine, but when I try to plot the whole table I get: Plot3D::plnc: Sincphase[(*)Sqrt(xx+yy), time] is \ neither a machine-size real number at x, y={20,20} \) nor a list of a real number and a valid color directive."\) ((*)Sqrt substituted for symbol) . as if the 'time' variable is not being evaulated. Am I doing something wrong?
