one way
out = oprtn_pts(:);
or
out = oprtn_pts.';
out = out(:);
other:
out = reshape(oprtn_pts,[],1);
or
out = reshape(oprtn_pts.',[],1);

oprtn_pts = randn(3,2);
oprtn_pts = reshape(a,6,1);
It takes the elements from oprtn_pts columnwise.

Wayne, I want to generalize this case. Now, let's assume that I don't know what is size of oprtn_pts. I am getting this size by using command s = size(oprtn_pts); Now say that s = m n (We don't know what is there inside). How can I convert this into 1-D array? Please suggest something on this.

Hi Andrei, Thanks a lot for the help. I din't refresh my page earlier, so wasn't able to see your response. Yeah, your response is working absolutely fine for me... :-)
