DOT

 

Syntax: @DOT(R1, R2)

R1= a vector
R2 = a vector

@DOT 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.

Examples:

Matrix 1, A1..B2 =

A B
1 1 3
2 2 4

Matrix 2, C1..D2 =

C D
1 9 5
2 2 4

@DOT(A1..B2, C1..D2) =44

@DOT(A1..B1, C1..C2) = 15

@DOT(A1..B2, D1..D2) = Error - @DOT, incompatible range dimensions
