MATLAB: Writing cellArray to doc file.

Question

[fileName, filePath] = uiputfile('*.doc', 'Create a file:')
if ~ischar(fileName)
  return;
end
fileID = fopen(fullfile(filePath, fileName), 'w');
coordinates=[32.56744567,33.54543333;32.55546543,33.77786567;32.66874567,33.44843753];
coordinates=num2cell(coordinates);
ids=[{'a'};{'b1'};{'3'}];
cellArray=[ids,coordinates];

%I need to write cellArray into word doc file with the same precision of coordinates.

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.
