# CxDotProduct

Advanced Analysis Library Only

AnalysisLibErrType CxDotProduct (ComplexNum vectorX[], ComplexNum vectorY[], int numberOfElements, ComplexNum *dotProduct);

## Purpose

Calculates the dot product of the complex input arrays. Use the following formula to obtain the dot product d:

## Parameters

Input
Name | Type | Description
vectorX | ComplexNum array | First complex input vector. The following C typedef statement defines the ComplexNum structure: typedef struct { double real; double imaginary; } ComplexNum;
vectorY | ComplexNum array | Second complex input vector. The following C typedef statement defines the ComplexNum structure: typedef struct { double real; double imaginary; } ComplexNum;
numberOfElements | integer | Number of elements in each vector.
Output
Name | Type | Description
dotProduct | ComplexNum | Complex dot product of the input vectors.

## Return Value

Name | Type | Description
status | AnalysisLibErrType | A value that specifies the type of error that occurred. Refer to analysis.h for definitions of these constants.
