New description:
Numpy and Scipy has functions to load matrix save in text files (Numpy:
http://docs.scipy.org/doc/numpy/reference/routines.io.html and Scipy:
http://docs.scipy.org/doc/scipy/reference/io.html).
Will be nice to have a Sage function to call some of this function as
backend and to handle with more file formats.
In attachment trac_13601-matrix_io.patch was suggest the follow formats:
* A single matrix in a text file without header or any other information.
* Coordinate Text File.
* Octave's binary data format.
* Octave's binary data format.
* hdf5 format.
* The Matrix Market (MM) exchange formats.
* The Harwell-Boeing format.
* Matlab format.
* IDL save file.
* Mathematical Programming System (mps).
Load Matlab and IDL format was implemented as a backend of Scipy and MPS
was implemented from scratch.
Load others suggest formats wasn't implemented. Neither the functions to
write.
'''To improve this module to handle with any of the not implemented
formats or any new format, please open other ticket.'''
Will be nice to implemented the suggest of [ticket:13601#comment:4
