latitude in decimal degrees, positive to the north of the equator. (This
is called lat in the TEOS-10 Matlab code.)

Implementation Note
This R function uses a wrapper to a C function contained within the GSW-C
system as updated 2022-10-11 at https://github.com/TEOS-10/GSW-C with
git commit `657216dd4f5ea079b5f0e021a4163e2d26893371`.
The C function uses data from the library/gsw_data_v3_0.mat
file provided in the GSW-Matlab source code, version 3.06-11.
Unfortunately, this version of the mat file is no longer displayed on the
TEOS-10.org website. Therefore, in the interests of making GSW-R be
self-contained, a copy was downloaded from
http://www.teos-10.org/software/gsw_matlab_v3_06_11.zip on 2022-05-25,
the .mat file was stored in the developer/create_data directory of
https://github.com/TEOS-10/GSW-R, and then the dataset used in GSW-R
was created based on that .mat file.
Please consult http://www.teos-10.org to learn more about the various
TEOS-10 software systems.
