01 Dec 2009	grdread2 Uses built-in netCDF capability to load a grid file created by GMT (Generic Mapping Tools) v3 or v4 Author: Kelsey Jordahl	It works for me on R2009b, at least on Mac OS X (maci64). It doesn't seem to work any differently from R2008b for me, but I haven't tried it yet on other platforms. Are you sure that you have a COARDS-compliant NetCDF grid generated by GMT version 4 or later? It will not work with grids generated by earlier versions of GMT, even though v3 was also NetCDF based, but it was not COARDS. I am working on an updated version of grdread2.m that will read these grids. Also, it will not necessarily work on more general COARDS-compliant NetCDF files generated by other programs, even though GMT may be able to read them.

26 May 2011	imshade Plot shaded relief, optionally using simulated lighting direction Author: Kelsey Jordahl	Klymak, Jody	Looks nice! A more general implementation of something similar can be seen in my submission: http://www.mathworks.com/matlabcentral/fileexchange/14157-shaded-pseudo-color
17 Dec 2010	grdwrite2 Uses built-in netCDF capability to write a grid file to be read by GMT (Generic Mapping Tools). Author: Kelsey Jordahl	Gong, Donglai	Need to update netcdf.create line in grdwrite2.m to work with R2010b. (i.e. the mode should be 'NC_SHARE' instead of 'NC_WRITE'). Otherwise work as advertised. Thanks!
15 Feb 2010	Haxby color map Create a colormap with Haxby's colors, commonly used for bathymetry and marine gravity data. Author: Kelsey Jordahl	Whitmire, Amanda	Perfect - exactly what I was looking for. Thank you for sharing!

03 Apr 2011	Color Palette Tables (.cpt) for Matlab Create and apply GMT-style colormaps in Matlab	Felipe G. Nievinski	Another one, trying cptcmap('sst') Just had to replace if ~strcmp(varargin{1}(end-3:end), '.cpt') % without extension for: if (numel(varargin{1}) <= 4) \|\| ~strcmp(varargin{1}(end-3:end), '.cpt') % without extension	Comment only

03 Apr 2011	Color Palette Tables (.cpt) for Matlab Create and apply GMT-style colormaps in Matlab	Felipe G. Nievinski	You might want to replace l.83: cptpath = './cptfiles'; with: cptpath = fullfile(fileparts(which('cptcmap')), 'cptfiles'); That way the source code needs not be modified when first downloading the package or later when moving the routine files around. I was having problems trying cptcmap('elevation') where elevation.cpt was downloaded from cpt-city and placed in the cptpath; it turns out that l.98, if exist(varargin{1}, 'file') % full filename and path given would find this other file instead: which elevation C:\Program Files\MATLAB\R2009b\toolbox\map\map\elevation.m You might want to replace the block l.98-111 with the following (minimally modified): if ~strcmp(varargin{1}(end-3:end), '.cpt') % without extension varargin{1} = [varargin{1} '.cpt']; end if exist(varargin{1}, 'file') % full filename and path given filename = varargin{1}; else % only file name given filename = fullfile(cptpath, varargin{1}); if ~exist(filename, 'file') error('Specified .cpt file not found'); end end Finally, not sure why the __MACOSX subdirectory is being distributed.

26 Mar 2011	Color Palette Tables (.cpt) for Matlab Create and apply GMT-style colormaps in Matlab	Felipe G. Nievinski	Great idea, always wanted to make my matlab maps look like gmt's. Also thanks for pointing out to cpt-city, it's a great collection. You might want to use the acknowledgement field in the FEX form, so that your submission is back-linked from related entries, e.g., 28982 and the ones linked from there.	5
