Hi Alexander, > I'm looking for netcdf software and installation for Matlab 7, to run > on my Mac OSX. Can you help me this? The library builds out of the box on Mac OSX from the source distribution: ftp://ftp.unidata.ucar.edu/pub/netcdf/netcdf.tar.gz but you can also get a pre-compiled binary distribution that will install more easily from here: ftp://ftp.unidata.ucar.edu/pub/binary/macosx_10.3_powerpc/netcdf-3.6.0-p1.pkg.zip You can get any of several freely available implementations of a MATLAB/netCDF interface by following the links here: http://www.unidata.ucar.edu/software/netcdf/software.html#MATLAB --Russ
