There are two parse errors in that code, both where you've forgotten a comma between indices 256 and the colon character.

plot(bath.longitude,bath.height(256:));

% and later

plot(bath.longitude,bath.height ((256:));

In the future, look for the red underlines in the right gutter when you've opened your code in the MATLAB Editor. These indicate where you've written something MATLAB can't understand that will prevent your code from running. Orange underlines are places where the Code Analyzer in MATLAB indicates there may be something you can do to improve your code. In both cases, there should be an underlined part of that line of code and hovering over it will indicate what MATLAB believes is wrong.

For more information on Code Analyzer, see this documentation page.
