The MATRIX program is designed to perform and to teach row operation algorithms on matrices. The program can work in a decimal floating-point mode in which calculations are carried out to 18 significant digits, or it can work in a fraction mode with exact rational arithmetic.
Defining a Cost Matrix. A cost matrix does two things. It defines the list of host computers that make up the abstract parallel machine that will run the HeNCE program, and it provides HeNCE with an estimate of the cost of running each of the program's subroutines on each of the hosts.
