Dear Srinivas Sri, for example you have coordinates in the form of 'x' and 'y' array then you can write it in a text file using "dlmwrite" function like this:

x = 1:20;
y = 2:2:40;
M = [x' y'];
disp(M)
dlmwrite(filename, M, '\t')

[srinivas sri]

i have tried the same one you sent me , but its saying that its undefined function...

[sixwwwwww]

Have you changed the "filename"?

[srinivas sri]

what file name should i write there..is it the text file i want the answer to be in .. or what ???

[sixwwwwww]

dlmwrite('MyCoordinates.txt', M, '\t')

[srinivas sri]

thank u very much...its working.. just out of curiosity - what if i want the matrix in a text file in matrix form itself.......

[sixwwwwww]

For matrix you can do the same. Just save all the values in a matrix (e.g. M) and then use:

dlmwrite('MyCoordinates.txt', M, '\t')

Also accept this answer to help others find solution of similar question. Good luck!

[srinivas sri]

if we are doing like that ,they are coming in a same line ,not row and column wise....

If you will open your file in "Notepad" then you will not see the actual matrix form but if you will open your file in "WordPad" or "Microsoft Word" then you can see it in matrix form
