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 A can be obtained by specifying a single ":" as the column index:
>>A(2,:)
ans =
6 7 8 9 10
A can be obtained by specifying a single ":" as the row index:
>>A(:,3)
ans =
3
8
13
18
