Changes since 1.1: +50 -0 lines
Merge from branch pre38:
 o essential mods for cubed sphere
 o debugged atmosphere, dynamcis + physics (aim)
 o new packages (mom_vecinv, mom_fluxform, ...)

1 function [varargout] = stats(A)
2 % stats(A) writes the basic statistics of the A to the terminal which
3 % are i) the minimum finite value
4 % ii) the maximum finite value
5 % iii) the mean of the finite values
6 % iv) the S.D. of the finite values ( RMS of [A-mean] )
7 % v) the fraction of non-finite elements excluded from calculations
8 %
9 % e.g.
10 % >> stats(topo)
11 % Min -4555 Max 0 Mean -2331.07 SD 1207.3441 N-Z 1024/1024
12 %
13 % [Min Max Mean SD]=stats(topo); returns the statistics in Min, Max,
14 % Mean and SD and does not write to the terminal.
