Hello Everyone,

I have attached two Scripts to this. One of the scripts processes (File named Single Single_FIle_GPP) spits the output I am looking for but I would want my code to do this with multiple files are selected.

Currently my output is of Two Columns and 80 Rows (max) from one file in a table format. In case of of multiple files I would want my next files output spaced by one column.

MultiFile_Input is the Incomeplete Script.

Could someone suggest an efficient indexing method Please.

Thanks

Add single and/or double whitespace to end of the existing completed table variable for single file input and process it for multiple files reading each file data sequentially in a loop

Important that table variables used for reading data must remain same for each input file

在 MATLAB Online 中打开

[filelist,pathn] = uigetfile('*.*','Please Select a Par File in .dat or .txt', 'multiselect', 'on');
if isnumeric(filelist); error('no file selected'); end
filelist = cellstr(filelist);      %take care of case where a single file was selected
filelist = fullfile(pathn, filelist);
for K = 1 : length(filelist)
    filename = filelist{K};
    %do the processing stuff here
    %....
    Complete_Table{K} = vertcat(TF_Standard_Table,TF_Performance_Table,TF_Tanker_Table,TF_Off_Road_Table);
end

At this point you have to decide how you want to put all of the tables together. In the general case, you cannot assume that TF_Standard is the same for all of the files. Maybe you want to do an inner join or something like that.
