2. Installing the GSW Oceanographic Toolbox in MATLAB

Step 1

Download the GSW Oceanographic Toolbox in MATLAB from www.TEOS-10.org.

Step 2

Unzip the Toolbox to a directory you name “GSW”.

ENSURE THAT ALL THE SUBFOLDERS (html, library, pdf)

HAVE BEEN EXTRACTED.

Step 3 (within MATLAB)

Add the “GSW” directory to your MATLAB path using “Add with subfolders …”

That is, use the menus as follows “File”

→

“Set Path…”

→

“Add with subfolders

…”.

(Alternatively, the “addpath” command could be used).

ENSURE THAT ALL THE SUBFOLDERS (html, library, pdf)

HAVE BEEN ADDED TO THE PATH.

Step 4

Run gsw_check_functions to check that the Toolbox is correctly installed and that

there are no conflicts. (This function runs three stored vertical profiles through all of

the GSW functions, and checks that the outputs are within pre-defined limits of the

correct values. These pre-defined limits are a factor of approximately a hundred larger

than the errors expected from the numerical precision of different computers, at the

standard double precision of MATLAB).

If the MATLAB Desktop is running,

Step 5

Run gsw_front_page to gain access to the front page of the GSW Oceanographic

Toolbox, which describes all aspects of the Toolbox.

Having installed the GSW Oceanographic Toolbox, the command gsw_contents will

show the contents list of the software functions. The software descriptions and the help

files for the GSW functions can be accessed by clicking on the function names on this list.

In addition, we have included a short demonstration function, gsw_demo, to introduce

the user to the GSW Oceanographic Toolbox. gsw_demo uses two stored

profiles from the North Pacific and demonstrates, in a step-by-step manner, how to

convert these into

profiles. gsw_demo then demonstrates how to evaluate

several water-column properties such as dynamic height, geostrophic streamfunction and

geostrophic velocity, as well as forming potential density contours on the

diagram.

A user may want to run gsw_check_functions periodically to confirm that the software

remains uncorrupted.
