[SciPy-user] What is fastest load/save matrix methods?

[Hugo Gamboa]

Hi there,

I need to work with large matrixes that come in ascii format.

I have the functions to build the matrix from the ascii file but it 
takes too long.
I can spend some time convert ingthis ascii files to some other format 
so that the re-readeing be fastened.

What is the fastest (binary) format readly available in scipy to 
load/save matrixes?

Thanks in advance for your attention.
