LabVIEW Tip of the Day 2019-01-01:

Matrix Size

Happy new year, fellow #labviewfriends! Let us start off 2019 by doing away with the following nuisance: Getting the size of a 2D array. Using the Array Size function, we need to index out the row and column sizes from its output, which is, as we already said, a bit of an annoyance.

But since LabVIEW 2009 (nearly 10 years!), the Matrix Size Function has been there for us:

Returns the dimensions for the number of rows and columns of matrix. The connector pane displays the default data types for this polymorphic function.

The awesome thing about this is: The matrix 2D array can be any numeric type or a real or complex matrix.

Note: Read Darren's Weekly Nugget on this function for more details and links to further resources.
