One way to do it is to use the Python functions on strings. For example, if
you want to use the real double field (RDF) and matrix_data is your string,
the following should do what you want:
M = matrix(RDF, [b.split() for b in matrix_data.split('\n')])
The split method of a string creates a list of substrings that are separated
by a given separator, and the default separator is whitespace.
See the documentation on RDF to see if you want to use that, or RR or
something else.
