a=dir('*.nc');

 for i=2:numel(a)
    nc_cat('ts_oaflux_1958.nc',a(i).name);
 end

 f=nc_varget('ts_oaflux_1958-2012.nc','tmpsf');

 d=find(f>30000);
 f(d)=nan;

when I run it I get this error:

 d =

   Empty matrix: 0-by-1

Thank u in advance.

What is the function nc_varget?

[lina]

to Retrieve data from a netCDF variable its a function from NETCDF tool box

[dpb]

I can't find any Matlab functions of those names--nor is there any TMW NETCDF Toolbox listed at the TMW web site.

This must be either Octave maybe or something from File Exchange or a vendor package???

So far, it doesn't seem to be a Matlab question.

the 0 sized matrix means that non of the elements of f are greater than 30000, so if you want solve the problem, try this:

d=find(f>30000);
if any(d)
  f(d)=nan;
end
