Creat a new nc file after filling the missing data using interpolation

Hello,

I was trying to fill the missing data using interpolation in a directory that has 100's of similar nc files. When I run the code, it went well. However, when I checked the data, all variables are filled with the same value in each variable. Would you please let me know what went wrong in the code? Thanks

% Specify the folder where the files are.
InFolder = 'Z:infolder';
filePattern = fullfile(InFolder, '*.nc'); 
inFiles = dir(filePattern);
outFolder = 'Z:infolder\new'

Loop for each nc-file

for i = 1:length(inFiles)
    baseFileName = inFiles(i).name;
    EDGEE = ncread(baseFileName,'EDGEE') ; 
    EDGEW = ncread(baseFileName,'EDGEW') ; 
    EDGES = ncread(baseFileName,'EDGES'); 
    EDGEN = ncread(baseFileName,'EDGEN') ;
    LONGXY = ncread(baseFileName,'LONGXY') ; 
    LATIXY = ncread(baseFileName,'LATIXY') ; 
    PSRF = ncread(baseFileName,'PSRF') ; PSRF = fillmissing(PSRF, 'linear') ;
    time = ncread(baseFileName,'time') ; time = fillmissing(time,'linear') ;
    TBOT = ncread(baseFileName,'TBOT') ; TBOT = fillmissing(TBOT,'linear') ;
    WIND = ncread(baseFileName,'WIND') ; WIND = fillmissing(WIND,'linear') ;
    RH = ncread(baseFileName,'RH') ; RH = fillmissing(RH,'linear') ;
    FLDS = ncread(baseFileName,'FLDS') ; FLDS = fillmissing(FLDS,'linear') ;
    FSDS = ncread(baseFileName,'FSDS') ; FSDS = fillmissing(FSDS,'linear') ;
    PRECTmms = ncread(baseFileName,'PRECTmms') ; PRECTmms = fillmissing(PRECTmms,'linear') ;
    zbot = ncread(baseFileName,'zbot') ; %for extracted data
%     ZBOT = ncread(baseFileName,'ZBOT') ; %for main dataset before extraction
