Stassen's matrix multiplication formulas
There are a total of seven multiplications, four additions, and four subtractions in Strassen's matrix multiplication.
Explanation:
What are the rules for the Strassen matrix multiplication
Write P1 = A; P2 = H; P3 = E; P4 = D. For P5 we will use Diagonal Rule i.e. (Sum the Diagonal Elements Of Matrix X ) * (Sum the Diagonal Elements Of Matrix Y ), we get P5 = (A + D)* (E + H)
