% Function verbose(level, message)
|
||
%
|
||
% verbose : shows current verbose level
|
||
% verbose(n): set the level to n
|
||
% verbose(n, message): displays the message if n <= current verbose level
|
||
%
|
||
% verbose(n, message, v1, v2, ...) behaves like sprintf(message, v1, v2, ...)
|
||
%
|
||
% Suggested levels:
|
||
% 1: important information
|
||
% 2: general information
|
||
% 3: debugging
