Thanks for the advice. I went to that link. It looks as though one enters N equations (in as many unknowns, presumably as "X_1, X_2, X_3...X_N") with all the known parameters, co efficients and unknowns all to the right of the = sign and being set equal to zero (Eg: Y_1, Y_2...Y_N). Then the program may find unique solutions, if any exist.
Is that more or less correct? Gene
