there is some wrong when i use read_srtm30plus follow the help on wiki.
my code is
ax=axis; % grab the lon/lat range
lon_range=ax(1:2);
lat_range=ax(3:4);
[xbathy,ybathy,zbathy]=read_srtm30plus(lon_range,lat_range,60);
the wrong message is
??? Undefined function or method 'ncgeodataset' for input arguments of type 'char'.
Error in ==> read_srtm30plus at 33
nc=ncgeodataset(url);
the NCTOOLBOX for Matlab (easy install at http://code.google.com/p/nctoolbox/), i can't down load the code.
thanks
