Platform | x64, Win32, .NET |

Purpose |
To get the dot-product of two numeric or logical vectors. |

Class |
Transformational function. |

Syntax |
FUNCTION DOT_PRODUCT(VECTOR_A, VECTOR_B) |

Description |
The type of the result is a scalar numeric (integer, real, or complex) or logical type and is the same type as each element of the one-dimensional array VECTOR_A. VECTOR_A and VECTOR_B are one-dimensional arrays with the same length. VECTOR_A is of numeric type or logical type. If VECTOR_A is numeric then VECTOR_B must be numeric (though perhaps not the same type) and if VECTOR_A is logical then VECTOR_B must be logical. |

Return value |
If VECTOR_A is integer or real then the result is the inner product of the two arrays (i.e. the sum of the products of corresponding elements). If VECTOR_A is complex then its conjugate is used in the inner product and the result is the complex value that is the sum of the terms. If VECTOR_B = VECTOR_A then the imaginary part of the result will be approximately zero. If VECTOR_A is logical then the result is the same as ANY(VECTOR_A .AND. VECTOR_B). If the vectors have size zero then the result is zero or false. |
