MATLAB: How to export result of the script to txt/doc file

MATLABscripttext file

I have a script with several sprintf commands. How to write them automatically to external text file after running the script?

Best Answer

Use the fopen (link) command to create a file identification number. Then use the file identification number in your fprintf (link) calls to print to a file.

Copy your sprintf calls to fprintf calls, since they use the same essential syntax, other than fprintf using the file identification number.

MATLAB: Writing cellArray to doc file.

If you are trying to write the cell array data to an MS Word file, then you should check out http://www.mathworks.com/matlabcentral/fileexchange/9112-writetowordfrommatlab in the MATLAB File Exchange for details on how to do this.

If you wish to simply write the data to a text file without loss of precision, then try something like

 if fileID>0
    for k=1:size(cellArray,1)
       for m=1:size(cellArray,2)
           % get the data type of the element in the cell array
           dataType = class(cellArray{k,m});
           % element data type determines how we write it to file
           if strcmpi(dataType,'char')
               fprintf(fileID,'%s\t',cellArray{k,m});
           elseif strcmpi(dataType,'double')
               fprintf(fileID,'%.10f\t',cellArray{k,m});
           % etc. for each data type in the cell array
           end
        end
        fprintf(fileID,'\n');
    end
    fclose(fileID);
 end

By using the %.10f we are requesting that ten digits beyond the decimal place be written to file.

MATLAB: Printing answers in a word doc

Fabiano - while you have given the extension of doc to your file, it won't be a Word document that you are creating but just at text file. Is this sufficient?

As for the reason as to why the file is empty, it is most likely because you haven't closed the file that is identified by fid. Use fclose to close the file once you have finished writing all text to the file as

 fclose(fid);
