      A lens is a custom view of Connexions content. You can think of it as a fancy kind of list that will let you see Connexions through the eyes of organizations and people you trust.

      What is in a lens?

      Lens makers point to Connexions materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Vectors and Arrays in LabVIEW MathScript

Module by: Anthony Antonacci, Darryl Morrell Based on: Vectors and Arrays in MATLAB by Darryl Morrell

Summary: This module provides a link to the Mathworks tutorial on vectors and arrays, and adds a useful piece of information not covered in the tutorial using LabVIEW MathScript.

Vectors and Arrays in LABVIEW MATHSCRIPT

An excellent tutorial on how to use LABVIEW MATHSCRIPT's vector and array capabilities is at the Inside LABVIEW MATHSCRIPT Tutorial. Here you can view the general use of LABVIEW MATHSCIRPT and find usefull information about data handling capabilities such as arrays and vecotrs.

One useful method of accessing entire rows or entire columns of the matrix is not mentioned in the tutorial. Suppose that the matrix A is defined as 

>>A = [1  2  3  4  5
        6  7  8  9  10
        11 12 13 14 15
        16 17 18 19 20]
A =

           1       2       3       4       5      
           6       7       8       9       10     
           11      12      13      14      15     
           16      17      18      19      20
An entire row of A can be obtained by specifying a single ":" as the column index: 
>>A(2,:)
ans =

           6       7       8       9       10
Similarly, an entire column of A can be obtained by specifying a single ":" as the row index: 
>>A(:,3)
ans =

           3      
           8      
           13     
           18
