Import Large Text File instructions

I've reread the instructions for using textscan from this page

http://www.mathworks.com/help/matlab/import_export/import-large-text-files.html

The site provides the following data, which has 2 blocks of data

## A  ID = 02476
## YKZ Timestamp Temp Humidity Wind Weather
06-Sep-2013 01:00:00  6.6  89  4  clear

What is the third figure for Block 3 plotting?

Answer 1

[dpb]

The first example reads the data in sets "blocks" of 5 repeats of the lines matching the format string. Since there are two groups of data with 6 and 7 lines, respectively, the third group read in fixed blocks of 5/block is the last three points of the thirteen total.
