Chapter 3 Analysis Library

The classes and subclasses in the function tree are described here.

• The Array Operations function panels perform arithmetic operations on 1D and 2D arrays.

–1D Operations, a subclass of Array Operations, contains function panels that perform 1D

array arithmetic.

–2D Operations, a subclass of Array Operations, contains function panels that perform 2D

array arithmetic.

• The Complex Operations function panels perform complex arithmetic operations. The

Complex Operations function panels can operate on complex scalars or 1D arrays. The real

and imaginary parts of complex numbers are processed separately.

–Complex Numbers, a subclass of Complex Operations, contains function panels that

perform scalar complex arithmetic.

–1D Complex Operations, a subclass of Complex Operations, contains function panels

that perform complex arithmetic on 1D complex arrays.

• The Statistics function panels perform basic statistics functions.

• The Vector & Matrix Algebra function panels perform vector and matrix operations.

Vectors and matrices are represented by 1D and 2D arrays, respectively.

• The Array Utilities function panels copy, initialize, and clear arrays.

•Miscellaneous is a class of function panels for miscellaneous Analysis Library functions.

The online help with each panel contains specific information about operating each function

panel.

Hints for Using Analysis Function Panels

With the analysis function panels, you can manipulate scalars and arrays of data interactively.

You will find it helpful to use the Analysis Library function panels in conjunction with the User

Interface Library function panels to view the results of analysis routines. When using the

Analysis Library function panels, remember the following things.

• The processing speed of the analysis functions is affected by the computer on which you are

running LabWindows/CVI. A numeric coprocessor, especially, increases the speed of

floating-point computations. If you are using an Analysis Library function panel and nothing

seems to happen for an inordinate amount of time, keep the constraints of your hardware in

mind.

• Many analysis routines for arrays run in place. That is, the input and output data can be

stored in the same array. This is very important to keep in mind when you are processing
