DOT(R1, R2)This function returns the dot product of two vectors. R1 must have the same number of rows and columns as R2, or R1 and R2 can be one-dimensional vectors of the same length. Parameters R1 A vector R2 A vector Examples Matrix 1, A1..B2 = A B 1 3 2 4 Matrix 2, C1..D2 = C D 9 5 2 4 DOT(A1..B2, C1..D2) =44 DOT(A1..B1, C1..C2) = 15 DOT(A1..B2, D1..D2) = Error - DOT, incompatible range dimensions |
