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

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).
