Computes the dot product of two vectors.

Name

Description

Specifies a vector or matrix of double-precision, floating-point or complex double-precision, floating-point numbers.

Specifies a vector or matrix of double-precision, floating-point or complex double-precision, floating-point numbers. b must be the same size as a.

dim

Specifies the order in which LabVIEW computes the dot product for matrices. dim is a scalar that accepts the following values.
