Question 24

LabVIEW arrays

Answer 24

collection of elements

Question 25

Auto-Indexing

Answer 25

loops can accumulate arrays

• for loops auto-index by default
• while loops output only final value

Question 26

Array functions

Answer 26

array size, initialize array, build array, array subset, index array, replace array subset

Question 27

Array size function

Answer 27

returns the number of elements in the input array; each output element describing a dimension size

Question 28

Build array function

Answer 28

Assembles multiple arrays or adds scalar elements to an array; concentrates multiple arrays; appends elements to an n-dimensional array

Question 29

Initialize array function

Answer 29

creates an n-dimensional array with elements containing a specified value; all elements are the same value

Question 30

Array subset function

Answer 30

returns a portion of an array; starts an index; contains “length” elements

Question 31

Index array function

Answer 31

gives access to an elements or sub-array in an array

Question 32

Replace array subset function

Answer 32

replaces an element or sub-array in an array at the point you specify in the index

Question 33

LabVIEW clusters

Answer 33

collection of elements; different data types; fixed size; al controls or all indicators

Question 34

Polymorphism

Answer 34

arithmetic functions accept inputs of different dimensions; outputs will be size of smaller array

Question 35

Cluster function

Answer 35

bundle or unbundle

Question 36

Graph

Answer 36

displays pre-generated arrays of data

Question 37

Chart

Answer 37

displays data by appending new data as it becomes available

Question 38

Single-plot

Answer 38

wire scalar ouput to waveform terminal

Question 39

Sweep chart

Answer 39

a moving vertical line marks the beginning of new data

Question 40

Scope chart

Answer 40

plot is erased when data points reach right border

Question 41

Strip chart

Answer 41

plot moves to the left as new data is added to the right

Question 42

X-Y Graph

Answer 42

plots data available at irregular intervals or plots two variables against each other

Question 43

Customizing charts and graphs

Answer 43

auto-scaling; x and y axes; plot legend; graph palette
