Details

if you are the developer, and you have some debug statements rather than comment them out, you can turn them off and on likewise, a user can request more or less informational comments

suggested standardized class codes for vprint():

-1 = developer debugging only

0 = constitutively turned on

1 = help for new user

2 = follow progress of long computation

3 = primary results

4 = meta info (e.g. dims of a mat before/after trimming)

5 = warnings

6 = errors

Note that the class argument is hardwired into the function code by the developer. For example, for a debugging statement, '-1' is hardwired in. The choice of whether or not to display this message is subsequently governed by the user selecting which values to include in the 'verbose' vector parameter.

Examples

vprint(1,1:2,"try me")
vprint(0,1:2,"try me")
vprint(3,1:2,"try me")
