  • Width block

Description

The Width block generates as output the width of its input vector.

You can use an array of buses as an input signal to a Width block. For details about defining and using an array of buses, see Combine Buses into an Array of Buses.

Ports

Input

expand all

Input signal specified as a scalar, vector, matrix, or N-D array.

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

Output

expand all

Output is the width of the input signal, specified as a scalar.

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

Parameters

expand all

Specify the output data type to be the same as the input, or inherit the data type by back propagation. You can also choose to specify a built-in data type from the drop-down list in the Output data type parameter.

Programmatic Use

Block Parameter: OutputDataTypeScalingMode
Type: character vector
Values: 'Choose intrinsic data type' | 'Inherit via back propagation' | 'All ports same datatype'
Default: 'Choose intrinsic data type'

This parameter is visible when you select Choose intrinsic data type for Output data type mode. Select a built-in data type from the drop-down list.

Programmatic Use

Block Parameter: DataType
Type: character vector
Values: 'double' | 'single' | 'int8' | 'uint8' | 'int16' | 'uint16' | 'int32' | 'uint32'
Default: 'double'
