get error when inputting data from csv file line by line;

Hello!

I tried to read a double-quoted csv file. This csv file was not in a good shape. It had multiple headers, blanks lines above the data part, so I have to do data input line by line.

CSV data looks like:

-------------------------------------------------------

"date:", "XX XX"

"Operator:", "XXXX"

" "

"XXXXXXXX", "XXXX", "YYYY", "NNNN"

"DataType", "NET"

"a", "b", "c", "d", .. "e"

"1", "2", "2", "3", .. "1"

"2", "2", "2", "3", .. "1"

"3", "3", "2", "3", .. "1"

"4", "2", "6", "3", .. "0"

"5", "2", "2", "3", .. "1"

...

" "

"other", "other"

...

----------------------------------------

My code starts reading data into variable 'NET' when the 1st column is a 'DataType' plus the 2nd colum is a 'NET'. (please see the following code).

variable 'NET' was set to [ ] by default (code: NET=[ ]). But when I use ( NET=[NET; line]; ), I got the following error:

??? Error using ==> vertcat

CAT arguments dimensions are not consistent .

I think I made mistakes in my code, but did not know how to fix it. Any help?

Thanks!!

 %code ------------------------------------------------;

 fid_t = fopen(...
    'C:datafile.csv', 'r');

 while ~feof(fid_t)
   temp1 = fgetl(fid_t); 
   temp2 = regexprep(temp1, '"', '');
   line = csv2cell(temp2);

   if strcmp(line{1}, 'DataType:')
       if strcmp(line{2}, 'Net')
           O2=line{2};
           fgetl(fid_t);

            NET=[];

           while ~feof(fid_t)
               tp1 = fgetl(fid_t);
               tp2 = regexprep(tp1, '"', '');
                line = csv2cell(tp2);     
               if isempty(line)
                  break;
               end
              NET=[NET; line];
           end

       end
   end
