B = flipud(A)
B = flipud(A) returns A with rows flipped in the up-down direction, that is, about a horizontal axis.
If A is a column vector, then flipud(A) returns a vector of the same length with the order of its elements reversed. If A is a row vector, then flipud(A) simply returns A.
If A is the 3-by-2 matrix,
A =
1 4
2 5
3 6then flipud(A) produces
3 6
2 5
1 4If A is a column vector,
A =
3
5
7then flipud(A) produces
A =
7
5
3The array being operated on cannot have more than two dimensions. This limitation exists because the axis upon which to flip a multidimensional array would be undefined.
