Hi
I'm having trouble plotting my netcdf file. I use pcolor, but the first time I tried I had noted Z'. This broke it over and said I should use permute I have done that now, now it comes with the error Matrix dimensions must agree. Why?
if true
filename='Januar79.nc'
%Read the header
ncdisp(filename)
%surf_temp
%Open the file in read only mode
ncid=netcdf.open(filename,'NOWRITE')
%inspect num of dimensions, variables, attributes, unim
[ndim, nvar, natt, unlim]=netcdf.inq(ncid)
for i=0:nvar-1
[varname, xtype, dimid, natt]=netcdf.inqVar(ncid,i);
if strcmp(varname,'surf_temp')==1
varnumber=i;
end
end
for i=1:length(dimid)
[dimname, dimlength]=netcdf.inqDim(ncid,dimid(1,i))
end
for i=0:nvar-1
[varname, xtype, dimid, natt]=netcdf.inqVar(ncid,i);
if strcmp(varname,'latitude')==1
dimnumber=i
end
end
latitude=ncread(filename,'latitude')
longitude=ncread(filename,'longitude')
Z=ncread(filename,'z')
pcolor(latitude,longitude,permute(Z, [2 1 3]))
load coast
hold on
plot(long,lat,'k','LineWidth',1.5)
plot(long+360,lat,'k','LineWidth',1.5)
end

Thank you really much! It's working for me now. What did you find out?

ncfile = 'C:\Users\srinivas\Downloads\Januar79.nc' ;
lon = ncread(ncfile,'longitude') ; nx = length(lon) ;
lat = ncread(ncfile,'latitude') ; ny = length(lat) ;
time = ncread(ncfile,'time') ;
for i = 1:length(time)
z = ncread(ncfile,'z',[1 1 i],[nx ny 1]) ;
pcolor(lon,lat,z') ;
shading interp
drawnow
end

Jonas Damsbo commented: It's not working. My .nc file is too big in this forum. Can I send to you on another platform?
