## again a surface-problem

 Hello, this is the correct diagram evaluated outside Octave: www.leobaumann.de/newsgroups/vertDipolOPG_MuPAD.jpg This is the wrong diagram evaluated with Octave: www.leobaumann.de/newsgroups/vertDipolOPG_Octave.png The problem is that the correct diagram shows a lot of lobes which are not shown in the with Octave evaluated diagram. Is that a problem of ezsurf() or did I make a mistake? I hope I have set the " .*, ./ " all correct this time. This is the Octave-script: clc; clear all; h=1/2;b2=12;l=1;wh=0; c=@(the,phi1) abs((cos(pi*h/l*cos(phi1))-cos(pi*h/l))./sin(phi1)) \                   *2 .*abs(cos(pi*2*(b2+h/2)/l*cos(phi1))); phi1=linspace (-pi/2, pi/2, 1000); polar(phi1+pi/2, c(wh,phi1)); set (gca, "rtick", 0.2:0.2:2, "ttick", 0:10:180); title ("Vertikaldiagramm"); #print("vertDipolOPG0.png", "-dpng"); input("weiter - ", "s"); ezsurf(@(the,phi1) c(the,phi1).*cos(the).*sin(phi1),\         @(the,phi1) c(the,phi1).*sin(the).*sin(phi1),\         @(the,phi1) c(the,phi1).*cos(phi1), [-pi, pi, -pi/2, pi/2] ,30); title ("Antennendiagramm"); axis equal; #print("vertDipolOPG_Octave.png", "-dpng"); Thanks - Regards - Leo _______________________________________________ Help-octave mailing list [hidden email] https://lists.gnu.org/mailman/listinfo/help-octave
