This seems a basic question: I've successfully configured the python gdb printer located at eigen/debug/gdb. I can stop at a break point and type 'p M' to print all elements of matrix M. But how can I print some elements of a matrix or vector? I've try 'p M[2,3]' and 'p M(2,3)' and that doesn't work.

Any one have some clue?
Thanks,

you probably have to do the addressing yourself, like:

p M.m_storage.m_data[2+3*<#rows>]
