CC-PC Histo Documentation

[ Up ]

This pages documents the interfaces of the histogramming package for the Credit-Card PC.

In a first part the interfaces (C and C++) are described. The second part describes lists example programs for the interfaces

Part 1 Interfaces

C Interface

The C Interface to the histogramming package is described here

C++ Interface

The C++ Classes are documented here.

Part 2 Example Programs
