Convert 2-D to 1-D

(To be removed) Convert 2-D matrix input to 1-D vector

The Convert 2-D to 1-D block will be removed in a future release. Use the Reshape (Simulink) block instead. When the block is removed, existing instances of this block will be automatically replaced with the Reshape block.

Description

The Convert 2-D to 1-D block reshapes an M-by-N matrix input to a 1-D vector that has a length of M*N.

y = u(:)					% Equivalent MATLAB code 

The input is reshaped column-wise for a 3-by-2 matrix.
