Saving cell array data from uitable using 'save'

I have the data from a uitable as:

inputdata = 

      '300'     [101.0366]    [0.7744]    [0.3806]
      '600'     [101.2867]    [0.4358]    [0.1959]
      '1000'    [101.2317]    [0.4522]    [0.1898]
      '2000'    [101.4917]    [0.5007]    [0.2892]
      '4000'    [101.6842]    [0.6338]    [0.4064]

I am trying to save to a text file, but the following doesn't work.

inputdata=(get(handles.uitableDark,'Data'))
save('C\:DarkFPN.txt','inputdata','-ascii');

Jason - since inputdata is a cell array, I suspect that you are observing the following error

 Warning: Attempt to write an unsupported data type to an ASCII file.
 Variable 'inputdata' not written to file.

Is this is true, what can you tell us about your data from the uitable. Your example has a mix of numeric datatype and character arrays (the first column). Can you convert this first column to doubles and so have a matrix all of the same data type? If so, then you will be able to use the above save function.

If not, then I would use the example from export cell array to text file which uses fprintf to write the data to file. Something like

 fid = fopen('myData.txt','w');
 if fid > 0
     [nrows,ncols] = size(inputdata);
     for row = 1:nrows
         fprintf(fid,'%s %f %f %f\n',inputdata{row,:});
     end
     fclose(fid);
 end

Try the above and see what happens!

Thanks Geoff

I had to use 'wt' and not 'w' to get the newline character to work

fid = fopen('myData.txt','wt');

I wondered about that. When I tried, I didn't need the text specifier. (R2014a, Mac OS)
