How can I convert 2-D array to 1-D array.

I am using a variable oprtn_pts. whose size is 3 2.

I want to convert this into 6*1. How can I do this?

Answer 1

[Andrei Bobrov]

one way

out = oprtn_pts(:);

or

out = oprtn_pts.';
out = out(:);

other:

out = reshape(oprtn_pts,[],1);

or

out = reshape(oprtn_pts.',[],1);

Answer 2

[Wayne King]

 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.
