Section: Array Generation and Manipulations
Reverses an array along the given dimension. The syntax for its use is
y = flipdim(x,n)
where x
is matrix, and n
is the dimension to reverse.
The following examples show some uses of flipdim
on N-dimensional arrays.
--> x = int32(rand(4,5,3)*10) x = (:,:,1) = 5 2 4 2 8 7 6 6 6 7 7 0 1 1 0 3 2 1 9 9 (:,:,2) = 10 6 3 3 1 1 2 5 7 10 9 7 5 1 4 3 10 4 4 3 (:,:,3) = 3 6 5 8 9 9 8 5 3 0 1 7 9 4 8 4 6 4 9 5 --> flipdim(x,1) ans = (:,:,1) = 3 2 1 9 9 7 0 1 1 0 7 6 6 6 7 5 2 4 2 8 (:,:,2) = 3 10 4 4 3 9 7 5 1 4 1 2 5 7 10 10 6 3 3 1 (:,:,3) = 4 6 4 9 5 1 7 9 4 8 9 8 5 3 0 3 6 5 8 9 --> flipdim(x,2) ans = (:,:,1) = 8 2 4 2 5 7 6 6 6 7 0 1 1 0 7 9 9 1 2 3 (:,:,2) = 1 3 3 6 10 10 7 5 2 1 4 1 5 7 9 3 4 4 10 3 (:,:,3) = 9 8 5 6 3 0 3 5 8 9 8 4 9 7 1 5 9 4 6 4 --> flipdim(x,3) ans = (:,:,1) = 3 6 5 8 9 9 8 5 3 0 1 7 9 4 8 4 6 4 9 5 (:,:,2) = 10 6 3 3 1 1 2 5 7 10 9 7 5 1 4 3 10 4 4 3 (:,:,3) = 5 2 4 2 8 7 6 6 6 7 7 0 1 1 0 3 2 1 9 9
