WebbThe product of A and B is C. The C (i, j) entry in matrix C can be calculated as the dot product of row i of A and column j of B. Example: C (1,1) = 3 * 1 + 4 * 3 = 15. Mathematically, we can express the formula as: C_ {r,c} = AB_ {r,c} = \sum_ {i=1}^ {n} A_ {r,i} * B_ {i,c} C r,c = ABr,c = i=1∑n Ar,i ∗Bi,c
