Description

The Constant block generates a constant value. The output size and type are defined by the block parameter.

Parameters

Constant_0

Name	Label	Description	Data Type	Valid Values
C	Constant	This parameter is a matrix of any type. The size of the matrix gives the size of the regular output port. The constant(i,j) value is the component(i,j) value of the output port.	Matrix
typ	Output datatype	This parameter defines the type of the output. Supported types are: Double, Complex, int8, int16, int32, uint8, uint16, uint32, boolean, inherit.	String	'double' 'complex' 'int32' 'int16' 'int8' 'uint32' 'uint16' 'uint8' 'boolean' 'inherit'
externalActivation	External activation	This parameter defines if the block receives an external activation or inherits. When External Activation is used, a additional activation port is added to the block. default is OFF.	Number	0 1
