There are functions in the package numericalio to read a matrix
(and some other kinds of objects). ? numericalio should find some
documentation (in Maxima 5.9.3 and later). The package name is
a misnomer -- actually the functions in that package can read
non-numeric atoms (symbols and strings) as well as numbers.
An input file is a plain text file with elements separated by spaces
(default), commas, or vertical bars (pipe symbol).
A : read_matrix ("path/to/mymatrix.data");
/* now do something with matrix A */
