Description

This block counts with an increment/decrement value equal to one from Minimum to Maximum or from Maximum to Minimum depending on the choice of the Rule parameter.

Data types

• Output: scalar double.

Dialog box

• Minimum

  The lowest number of the counter.

  Properties : Type 'vec' of size 1.

• Maximum

  The highest number of the counter.

  Properties : Type 'vec' of size 1.

• Rule (1:Increment, 2:Decrement)

  The rule of counting :

  • 1: Counts from the lowest number to the highest number. The count is increasing.

  • 2: Counts from the highest number to the lowest number. The count is decreasing.

  Properties : Type 'vec' of size 1.

Default properties

• always active: no

• direct-feedthrough: no

• zero-crossing: no

• mode: no

• regular outputs:

  - port 1 : size [1,1] / type 1

• number/sizes of activation inputs: 1

• number/sizes of activation outputs: 0

• continuous-time state: no

• discrete-time state: yes

• object discrete-time state: no

• name of computational function: counter
