There are at least four data struts in pandas.
->Slice
->DateFrame
->DateMatrix
->Panel
What are the use cases for these. The documents seem to highlight slice and DataFrame. Please give examples of use cases. I know where the doc is located.
The 3 main data structures are Series (1-dimensional), DataFrame (2D), and Panel (3D) (http://pandas.pydata.org/pandas-docs/stable/dsintro.html). A DataFrame is like a collection of Series while a Panel is like a collection of DataFrames. In many problem domains (statistics, economics, social sciences, ...) these are the 3 major kinds of data that are dealt with.

Also, DataMatrix has been deprecated. In pandas >= 0.4.0, DataMatrix is just an alias for DataFrame.
