Copy the same rows from multiple identical files to a single file

Hello,
I have 300 files which have similar structure. I am interested in rows 82-nd and 90-th in each file.
The 82-nd row is:
# span 1 = -0.193, 1.980
The 90-th row is:
# span 9 = 0.000, 557.000
I would like to copy the last number from rows 82 and 90 next to each other, also append those values from each file, like so:
output-file:
1.980 557.00
2.568 687.50
1.158 496.03
............
It would also be fine if I could copy the 82nd and 90th row to new single file and "append" the next files to that single file.
Like so:
# span 1 = -0.193, 1.980
# span 9 = 0.000, 557.000
# span 1 = -0.193, 2.568
# span 9 = 0.000, 687.50
# span 1 = -0.193, 1.158
# span 9 = 0.000, 496.03
....

Sicne you have not attached any sample file, I am using a file having 5 rows, and extracting 2nd and 5th rows from these. Attached these files for your reference.
F=dir('*.txt')
Row = [2,5];
formatSpec = '%1s%5s%2s%2s%12s%11s%s%[^\n\r]';
for kk=1:length(F)
fileID = fopen(F(kk).name,'r');
dataArray = textscan(fileID, formatSpec, 2, 'Delimiter', '', 'WhiteSpace', '', 'HeaderLines', Row(1)-1, 'ReturnOnError', false, 'EndOfLine', '\r\n');
A{kk}=cat(2,dataArray{:});
end
out=cat(1,A{:})
%copying the last number in a matrix
mat=reshape(str2double(out(:,6)),2,[])'
%saving the rows in a text file
dlmcell('sample.txt',out)

I forgot to mention. You will get this function on a file exchange.
