I am trying to write ruby interfaces to a piece scientific computation library I wrote. This library itself uses other open-source libraries like OpenCV, boost etc. The primary data structure my library operates on, and that is being returned by my library, is an n-dimensional array type. Hence I was looking into which appropriate ruby objects this data type will map into. There is the native ruby array type, but I also found out the more mathematically powerful Nmatrix type.
Can someone point me to the documentation for the C/C++ api for nmatrix? Googling around for the C api docs did not help. I found some docs here http://sciruby.com/nmatrix/docs/ and the code repos on github here https://github.com/SciRuby/nmatrix and so far have been using the source code as the docs.
A few examples would be nice too.
