Running the Same code for Multiple Files in a Folder
显示 更早的评论
Hi,
tt10001 = readtable('10001.xlsx');
dsa = tt10001;
modelspec = 'Street ~ Catch*BackUp*PRCP - Catch:BackUp:Break:Manhole:PRCP';
mdl10001 = fitglm(dsa,modelspec,'Distribution','poisson')
I have multiple excel files (almost 200), such as "10001.xlsx" in a folder. The spreadsheets are of various zip codes, such as "10002.xlsx", "10003.xlsx"...
How can I run this code for every file in the folder?
And have the results "mdl10001.CoefficientCovariance" of each file exported to its own Excel spreadsheet, as in xlswrite?
Thanks. I'd very much appreciate any help with this.

indir = '.'; %path to input directory
outdir = 'results'; %path to where to put the results
if ~exist(outdir, 'dir'); mkdir(outdir); end
dinfo = dir(fullfile(indir, '*.xlsx'));
filenames =
nfiles = length(filenames);
for K = 1 : nfiles
thisfile = filenames{K};
infile = fullfile(indir, thisfile);
outfile = fullfile(outdir, thisfile);
tt10001 = readtable(infile);
dsa = tt10001;
modelspec = 'Street ~ Catch*BackUp*PRCP - Catch:BackUp:Break:Manhole:PRCP';
mdl10001 = fitglm(dsa, modelspec, 'Distribution', 'poisson');
outdata = mdl10001.CoefficientCovariance;
writematrix(outdata, outfile); %needs R2019b or later
end
If you are using earlier than R2019b then the last few lines would be
outdata = mdl10001(:,'CoefficientCovariance'); %the sub-table!
writetable(outdata, outfile);

Sorry, I amn not sure what happened there,
filenames = {dinfo.name};
Can you attach a sample .xlsx for testing?

10004.xlsx fails because it does not contain a column for "Break"
