# 1.4 Arrays in labview

 Page 1 / 1
Learn how to create and manipulate arrays, perform mathematical operations on them, and use spreadsheets to read and write arrays to thefile system.

## Overview

Arrays are a fundamental data type for signal processing. LabVIEW offers a complete set of techniques to create and manipulate arrays, and to perform mathematical and signal processing operations on arrays. This module will acquaint you with the basic techniques for working with arrays.

## Creating arrays

The following video screencast describes how to create arrays on the front panel and on the block diagram. The elements of an array can be edited and modified directly, a suitable technique when the array is relatively small.

## Manipulating arrays

The next video screencast explains essential array manipulations for signal processing tasks, including: determining the dimensions of an array, retrieving individual elements, rows, columns, or other subarrays , appending (concatenating) arrays, and reshaping arrays.

## Mathematical operations with arrays

Signal processing operations commonly operate on all of the array elements at once. For example, adding a scalar constant to an array implies a loop operation in which the constant is added to each element of the array.

The following screencast video describes several techniques for performing mathematical operations on arrays. Important side effects (such as what happens when two arrays of different lengths are added together) are discussed. The Ramp Pattern subVI is also described as a method to create a time basis for mathematical functions such as the exponential .

Spreadsheets are often used as a data storage mechanism by other applications. The next screencast video shows you how to retrieve an array from a comma-separated-values (CSV-format) spreadsheet, and how to create your own CSV-format spreadsheet from an existing array within LabVIEW.

what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
Damian
Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
Renato
What fields keep nano created devices from performing or assimulating ? Magnetic fields ? Are do they assimilate ?
why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
Joe
anyone know any internet site where one can find nanotechnology papers?
research.net
kanaga
sciencedirect big data base
Ernesto
Introduction about quantum dots in nanotechnology
what does nano mean?
nano basically means 10^(-9). nanometer is a unit to measure length.
Bharti
do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?
absolutely yes
Daniel
how to know photocatalytic properties of tio2 nanoparticles...what to do now
it is a goid question and i want to know the answer as well
Maciej
Abigail
for teaching engĺish at school how nano technology help us
Anassong
Do somebody tell me a best nano engineering book for beginners?
there is no specific books for beginners but there is book called principle of nanotechnology
NANO
what is fullerene does it is used to make bukky balls
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
NANO
so some one know about replacing silicon atom with phosphorous in semiconductors device?
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Harper
Do you know which machine is used to that process?
s.
how to fabricate graphene ink ?
for screen printed electrodes ?
SUYASH
What is lattice structure?
of graphene you mean?
Ebrahim
or in general
Ebrahim
in general
s.
Graphene has a hexagonal structure

On having this app for quite a bit time, Haven't realised there's a chat room in it.
