Description

The Flip block vertically or horizontally reverses the M-by-N input matrix, u. The block determines the dimension to flip along using the Flip along parameter.

This block supports Simulink® virtual buses.

Ports

Input

expand all

Input signal, specified as a matrix of size M-by-N.

Data Types: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32 | Boolean | fixed point | enumerated

Output

expand all

Flipped output, returned as a matrix of size M-by-N. The output always has the same dimensionality as the input.

Data Types: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32 | Boolean | fixed point | enumerated

Parameters

expand all

Specify the dimension along which to flip the input as Columns or Rows. When you set this parameter to Columns, the block flips the input vertically. When you set this parameter to Rows, the block flips the input horizontally.

When you set this parameter to Columns, the block flips the input vertically so the first row of the input becomes the last row of the output.

y = flipud(u) % Equivalent MATLAB code

When flipping the input vertically, the block treats length-M unoriented vector inputs as M-by-1 column vectors.

When you set this parameter to Rows, the block flips the input horizontally so the first column of the input becomes the last column of the output. 

y = fliplr(u) % Equivalent MATLAB code

When flipping the input horizontally, the block treats length-N unoriented vector inputs as 1-by-N row vectors.
