Description
Block Constant generates a valid or complex signal of constant value.
The block generates an output signal in the form of a scalar, vector, matrix or bus depending on the dimension of the parameter. Constant value.

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

Parameters
Main
# Constant value — the value of the constant
Details
Set the output to a constant value of the block.
You can enter any value, including logical keywords. true and false.

#
Sample time —
the interval between the calculation steps
SampleTime (real number / vector of two real numbers)
Details
Sets the time interval during which the block output signal is Constant it may change during simulation (for example, due to parameter settings Constant value).
Default value inf indicates that the block output can never change. This value speeds up the simulation and the generated code, avoiding the need to recalculate the block output.
