Remove singleton dimensions from multidimensional signal

  • Simulink / Math Operations

  • Squeeze block

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.

Ports

Input

expand all

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.

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