large amounts of data. Large double-precision arrays consume a lot of memory. If the

results you want do not require that you keep the original array or intermediate arrays of data,

perform analysis operations in place where possible.

• The Interactive window maintains a record of generated code. If you forget to keep the code

from a function panel, you can cut and paste code between the Interactive and Program

windows.

The functions in the Analysis Library return status information through a return value.

If the return value status is zero after an Analysis Library function call, the function properly

executed with no errors. Otherwise, status is set to the appropriate error value. Error messages

corresponding to the possible status values are listed at the end of this chapter.

Analysis Library Function Reference

This section describes each function in the LabWindows/CVI Analysis Library. The

LabWindows/CVI Analysis Library functions are arranged alphabetically.

int status = Abs1D (double inputArray[], int numberofElements,

double outputArray[]);

Purpose

Finds the absolute value of the inputArray. The function performs the operation in place;

inputArray and outputArray can be the same array.

Parameters

Input inputArray double-precision

array Input array.

numberofElements integer Number of elements.

Output outputArray double-precision

array Absolute value of input array.
