Wrapper to WFDB SQRS:
Creates a SQRS annotation file at the current MATLAB directory.
The annotation file will have the same name as the recorName file,
but followed with the *.qrs suffix. Use RDANN to read the annoations
into MATLAB's workspace in order to read the sample QRS locations.
If recordName is the path to a record at PhysioNet's database, than
the annation files will be stored in a subdirectory with the same relative
path as recordName and under the current directory.
NOTE: In order to read the generated annotation file using RDANN, it is
necessary to have the WFDB record (*.hea and *.dat) files in the same
directory as the annotation file.
String specifying the name of the record in the WFDB path or
in the current directory.
Optional Parameters are:
A 1x1 integer specifying the sample number at which to stop reading the
record file (default read all = N).
A 1x1 integer specifying the sample number at which to start reading the
annotion file (default 1 = begining of the record).
A 1x1 integer. Specify the singal to obtain the annotation (default
= 1, first signal).
A 1x1 integer. Specify the detection threshold (default = 500).
Use higher values to reduce false detections, or lower values to
reduce the number of missed beats.

corrections of the Pascal original by WAH Engelse and Cees Zeelenberg.
