Hi, I am studying Matrix chain Multiplication to find out the optimal way of multiplying a series of matrices so that we can reduce the number of multiplications. I have got this example from the book which multiplies the matrices having dimensions given below: A1 30 * 35 A2 32 * 15 A3 15 * 5 A4 5 * 10 A5 10 * 20 A6 20 * 25 From these matrices, it creates the 2 tables: The algorithm is given below: MTM(A, s, I, j) If j> i Then Xß MCM(A, s, I, s[I,j]) Y ß MCM(A, s, s[I,j] + 1, j) return MCM (X, Y) else return Ai They are invoking the algorithm by: MCM(A, s, 1, 6) Can some body guide me what is the value of A & s? After that i want to find out the best way of ordering these matrices for multiplication. Some body please guide me. Zulfi.
