Constant

A constant value in the form of a real or complex scalar, vector, matrix or bus. By default, the Constant block outputs a signal whose dimensions, data type and complexity are the same as those of the Constant value parameter.

Data types: Float16, Float32, Float64, Int8, Int16, Int32, Int64, Int128, UInt8, UInt16, UInt32, UInt64, UInt128, Bool, Fixed point, BusSignal.

Support for complex numbers: Yes

Set the constant value output of the block.

You can enter any expression that will be treated as a matrix, including the logical keywords true and false.

Specifies the time interval during which the output of the Constant block may change during the simulation (e.g. due to the setting of the Constant value parameter).

The by default value inf specifies that the block output can never change. This value speeds up the simulation and the generated code by avoiding the need to recalculate the block output.

Specify the type of the output data. The type can be inherited, specified directly, or expressed as a datatype object.

Specify the output type of fixed-point numbers.

Dependencies

Turns ON when the Output data type parameter is set to Fixed point.

Describes the type of bus the block outputs.

Dependencies

To specify the output bus type, set the Output data types parameter to BusSignal. After that, the Output bus type field will appear in which you must enter the bus type (BusSignal{…}). You can write the type yourself or enter the name of a variable that stores the type already created in vorkspace.
