The current avilable pattern is as follows,
0.0,A
2.0,B
5.00,C
0.10,D
5.00,E
0.10,F
1.00,G
0.10,H
10.00,I
0.10,J
2.0,K
2.0,L
2.0,M
5.00,N
0.10,O
10.00,P
0.10,Q
The required pattern is as follows,
0.0,A
0.10,D
0.10,F
0.10,H
0.10,J
0.10,O
0.10,Q
1.00,G
2.0,B
2.0,K
2.0,L
2.0,M
5.00,C
5.00,E
5.00,N
10.00,I
10.00,P

You could download my FEX submission natsort:
And then import your file into a cell array of character vectors C:
C = regexp(fileread('new.txt'),'\S+','match');
D = natsort(C,'\d+\.?\d*'); % sort into the requested order.
Where D contains the sorted character vectors, which you can check:
>> D(:)
ans =
'0.0,A'
'0.10,D'
'0.10,F'
'0.10,H'
'0.10,J'
'0.10,O'
'0.10,Q'
'1.00,G'
'2.0,B'
'2.0,K'
'2.0,L'
'2.0,M'
'5.00,C'
'5.00,E'
'5.00,N'
'10.00,I'
'10.00,P'
If you want, save it to file:
[fid,msg] = fopen('out.txt','wt');
assert(fid>=3,msg)
fprintf('%s\n',D{:});
fclose(fid);

"Can you help me on this issue."
Of course. Here is the very first sentence of my answer:
"You could download my FEX submission natsort:"
Did you DOWNLOAD my FEX submssion from the link that I gave you? You will then need to unzip it into the current folder (or somewhere on the MATLAB Search Path).

T = readtable('new.txt')
T = sortrows(T)
writetable(T,'new2.txt','delimiter',',','WriteVariableNames',0)

Note that this method changes the numeric data format, the output file looks like this:
0.1,D
0.1,F
0.1,H
0.1,J
0.1,O
0.1,Q
1,G
2,B
2,K
2,L
2,M
5,C
5,E
5,N
10,I
10,P
Given the varaible number of trailing digits, it would be fiddly to make this work using writetable. The answer I provided gives the data in exactly the format shown in the question (i.e. unchanged from the input format).
