% With [MAXTAB, MINTAB] = PEAKDET(V, DELTA, X) the indices | |
% in MAXTAB and MINTAB are replaced with the corresponding | |

Settings for root logger. | |
Log messages will be printed to console and also to log file (rotated, with | |
specified size). All log messages from used libraries will be also handled. | |
Three approaches for defining logging settings are used: | |
1. using logging classes directly (py25+, py30+) | |
2. using fileConfig (py26+, py30+) | |
3. using dictConfig (py27+, py32+) | |
Choose any variant as you like, but keep in mind python versions, that |
