Sub1D

AnalysisLibErrType Sub1D (double arrayX[], double arrayY[], int numberOfElements, double outputArray[]);

Purpose

Subtracts two 1D arrays, element by element. Sub1D can obtain the element of the output array using the following formula:

zi = xi – yi

Sub1D can perform the operation in place; that is, the input and output arrays can be the same.

Parameters
