I am trying to read the following text file:

Using
fid=fopen('Arabsat 2B.txt');
A=textscan(fid,'%s');
Data=reshape(A{1}(1:end,:),9,[])';
fclose(fid);
format long g;
l1=Data(1:2:end,:);
l2=Data(2:2:end,:);
I was able to read another almost similar text file but when I try to run the code i get the error:
Error using reshape
Product of known dimensions, 9, not divisible into total number of elements, 56085.
Error in getTLE2 (line 10)
Data=reshape(A{1}(1:end,:),9,[])';
Kindly help that where am i going wrong.

The problem is in the text file you try to import.
Line 10 (2 24652 003.9626 209.9743 7275563 179.0821 184.3511 02.27899371000049) has only 8 numbers...

complete with nan
fid=fopen('filee1.txt');
A=textscan(fid,'%s');
fclose(fid);
d=A{:}
n=rem(numel(d),9)
if n>0
d(end+1:end+9-n)=num2cell(nan)
end
Data=reshape(d (1:end,:),9,[])';
format long g;
l1=Data(1:2:end,:);
l2=Data(2:2:end,:);

For reshape to work the total number of elements should be divisible by the factor you are reshaping it by.
I n your case you have 56085 element and you are tring to reshpe it by factor 9 which will not work since 56085/9 is 6231.66
it is divible definitely by 5 so
Data=reshape(A{1}(1:end,:),5,[])'
should work
