Some new/more scripts for plotting cube stuff.

1 function [X] = longitude(x)
2 % X=longitude(x);
3 %
4 % tries to determine best range of longitude (e.g. -180<180 or 0<360)
5 % so that coordinate (x) doesn't span a discontinuity.
6 %
7
8 % also works for radians which are assumed if range of x<=2*pi
9
10 minx=min(min(min(x)));
11 maxx=max(max(max(x)));
12 %if maxx-minx < 2.2*pi
13 % units=180/pi;
14 %else
15 units=1;
16 %end
17 minx=min(min(min(x*units)));
18 maxx=max(max(max(x*units)));
19
20 X=mod(720+x*units,360);
21 maxP=max(max(max(X)));
22 minP=min(min(min(X)));
23
24 XX=mod(X+180,360)-180;
25 maxM=max(max(max(XX)));
26 minM=min(min(min(XX)));
27
28 if maxP-minP > maxM-minM
29 X=XX;
30 end
