If you save a matrix object to a file, you can then load it into Sage.
For example:

MS = MatrixSpace(base_ring = IntegerModRing(100), nrows = 12, ncols = 12)
mat = MS.random_element()
mat.save("matrix.dat")  # saving mat to file "matrix.dat.sobj"
m = load("matrix.dat")  # loading mat from file; mat and m represent
the same matrix

Hope that helps.
