Description

The Squeeze block removes singleton dimensions from its multidimensional input signal. A singleton dimension is any dimension whose size is one. The Squeeze block operates only on signals whose number of dimensions is greater than two. Scalar, vector, and matrix signals pass through the Squeeze block unchanged.

Open Model

This example shows a model using the Squeeze block to eliminate a dimension of size 1.

The Squeeze block converts a multidimensional array from the Constant block of size 3-by-1-by-2 into a 3-by-2 signal.

Ports

Input

Input signal that has any singleton dimensions removed in the output.

Data Types: half | single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point | enumerated | bus

Output

expand all

Output signal with no singleton dimensions. For example, a multidimensional array of size 3-by-1-by-2 changes into a 3-by-2 signal. If there are no singleton dimensions in the input, then the input signal is passed through unchanged to the output.
