I wasn't aware of these functions in commercial Macsyma; I agree,
reproducing them seems to be the way to go.
1. The commercial Macsyma functions don't work with CSV files -- I think
elements need to be separated by spaces, tabs, or linefeeds? Because of
this,
and since some (human) languages use a comma for a decimal point, should
the Maxima functions also require that elements be separated by just
spaces, tabs, or linefeeds and not possibly by commas?
2. The function read_num_data_to_matrix requires the user to give the
matrix size. Would it be better to make the size arguments optional and
when they aren't given to have each line of the input file be a matrix
row?
Eventually (not in the next week or so) I'll try writing functions
read_numerical_data & friends; if anybody does before I get around to it,
that would be great!

The commercial Macsyma has the functions:
READ_NUMERICAL_DATA,
READ_NUM_DATA_TO_MATRIX and
READ_NUM_DATA_TO_ARRAY.
Perhaps for compatibility, they should be reproduced.
