Hi
I am getting so dizzy, i wrote a code and i want to record a table named 'DI' into a text file. I follow the instructions that is given here http://www.mathworks.com/help/matlab/ref/fprintf.html , but unfortunately it writes something quite different from the original table. I doubted that the code is wrong so i used the example that is given in the above link in my code and it gives me totally right answers.
The code that i use for this text writing is
fileID=fopen('ParkAngDI11.txt','w+');
fprintf(fileID,'%6s %12s\r\n','Time','Damage Index');
fprintf(fileID,'%6.2f %12.8f\r\n',DI);
fclose(fileID);
I would be so thankful if you help me through this.

The Table contains somee numbersd that is irrelevant with the original table that exists in matlab.
some the datas from original table is
0.0100000000000000 0
0.0200000000000000 0
0.0300000000000000 0
0.0400000000000000 0
0.0500000000000000 0
0.0600000000000000 0
0.0700000000000000 0
0.0800000000000000 0
0.0900000000000000 0
0.100000000000000 0
and it the first column continues to 39.98 and second column takes some values corresponding to column one.
the data that matlab writes for me is
Time Damage Index
0.01 0.02000000
0.03 0.04000000
0.05 0.06000000
0.07 0.08000000
0.09 0.10000000
0.11 0.12000000
0.13 0.14000000
0.15 0.16000000

39.91 39.92000000
39.93 39.94000000
39.95 39.96000000
39.97 39.98000000

My guess: column-wise. Change
fprintf(fileID,'%6.2f %12.8f\r\n',DI);
to
fprintf(fileID,'%6.2f %12.8f\r\n',transpose(DI));

Thank you so much dear Per Isakson your solution worked, Can you tell me why is this happening?!

Column-wise is the key to understand why. fprintf reads column-wise from the input matrix and writes "row-wise" to the file controlled by the format specification. Remember: Matlab is "column-first-oriented". Try
clc
M = [ 11, 12; 21, 22 ]
disp('-- fprintf --')
fprintf( 1, '%4d,%4d\n', M )
result in the command window
M =
11 12
21 22
-- fprintf --
11, 21
12, 22
