This program reads in two spaces from
Space1 and
Space2 and writes out their sum and intersection, in semi-echelon form, to
Sum and
Int, respectively. The input files must be matrices over the same field and with the same number of columns. They need not be in echelon form.
There must be enough memory to hold two copies of each of the two spaces at the same time.
