It might if I had used this for all of my c++ code, but I have a big library of c++ wrapped code that doesn't use pyublas. Pyublas takes numpy objects from python and allows the use of c++ ublas on it (without conversion). Most of my code doesn't use numpy, it uses plain ublas to represent vectors, and ublas handles storage. I can only interface to/from numpy with conversion. I'm interested in pyublas, but devel seems very quiet for a while. _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
