# Reverse

Advanced Analysis Library Only

AnalysisLibErrType Reverse (double inputArray[], int numberOfElements, double outputArray[]);

## Purpose

Reverses the order of the elements of the input array using the following formula:

yi = xn – i – 1

for i = 0, 1, . . ., n – 1

Reverse can perform the operation in place; that is, the input and output arrays can be the same.

## Parameters

Input

inputArray | double-precision array | Input array whose elements are placed in reverse order in the output array.
numberOfElements | integer | Number of elements to reverse.
Output
Name | Type | Description
outputArray | double-precision array | Reversed array.

## 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.
