Data Frames and Matrizes in C++

[Martin Thomson]

Hello!

1. How are data frames and matrizes typically realized in C++?
2. Is there a widely accepted standard for data frames and matrizes, which is used to pass and retrieve data to and from quantitative libraries (like quantlib for instance)?

Thanks
Martin

What do you want to do with matrices?

"matrizes' does not exist IMO

Any data structure you can think of can be implemented however you want.

For a matrix, create a vector of a vector.

2) any of these:

Eigen
Armadillo: C++ linear algebra library

1) data frame library in C++

Instead of home-grown matrices, Boost ublas is OK for common-or-garden work.

I like the ones mentioned by @pingu instead of boost uBlas.
