NumFiles=length(files);
%FMF_S=zeros(31,1);
for m=1:NumFiles
filename=files(m);
filename=char(filename);
data=hdfread(filename,'Ice_Water_Content_Profile'); %reading ice water dataset
lat=hdfread(filename,'Latitude');
lat=double(squeeze(lat(:,1)));
data(data==-9999)=nan; %removing fill value
data(data<0 | data>0.54)=nan; %removing out of range values
% data(data==0)=nan;
data(m,:)=data;
end
say i have three files, a.hdf anf b.hdf and c.hdf, i want the data should be added up in each case , and data matrix dimention remains the same. say for the first file data=846x399 double, when all the three files added up, matrix will remain the samr, i.e, 846x399 double but the three files data shall added up. how to do it with loop? I am getting "Subscripted assignment dimension mismatch." when i use my code,
