The problem about matlab package and seagrid package

[duckweed]

Hi,
i have some question about matlab package and seagrid package,as follows:
1) how to use the matlab package? And,what is the use of matlab package?
2) how to create a bathmetry file?
3) when i have a seagrid file, how to conversion it to netcdf format? by roms_cdl? how to do? please reply detailed

thanks a lot!

hi
just you do these things
i have used seagrid matlab program in windows
you download the seagrid matlab software and put it in matlab path.
you must add the mexcdf tools for your suitable matlab version
for extracting coastline data for your region, go through this path
https://www.myroms.org/wiki/index.php/seagrid
for getting bathymetry data, go through this path
http://www.ngdc.noaa.gov/mgg/gdas/gd_designagrid.html
after getting the data, you load data in matlab by using the commands
load filename
for coast line
lat=filename(:,1)
lon=filename(:,2)
save filename lat lon (you put whatever your interest file name for saving)
it create the coastline.mat file
it is the coast line input data for seagrid
for bathymetry
xbathy=filename(:,1)
ybathy=filename(:,2)
zbathy=filename(:,3)
save filename xbathy ybathy zbathy (you put whatever your interest filename for saving)
it creates the bathy.mat file
it is the bathymetry input data for seagrid
next you follow the seagrid tutorial
save seagrid
next onecommand is there it is
seagrid2roms
it will generate roms input gridfile in the nc format
ok bye
have a nice day

Please don't double post like this. If we're going to answer, we'll answer the first. I'm not going to answer this because I don't use Matlab.

There are other places where to learn matlab, and that is probably a good place to start.
