Description

The Logical Operator block performs the specified logical operation on its inputs. An input value is TRUE (1) if it is nonzero and FALSE (0) if it is zero.

Dialog box

• number of inputs
  The number of block inputs. The value must be appropriate for the selected operator.
  Properties : Type 'vec' of size 1

• Operator: AND
  The logical operator to be applied to the block inputs. Valid choices are the operators from the list.
  Properties : Type 'vec' of size 1

Default properties

• always active: no
• direct-feedthrough: yes
• zero-crossing: no
• mode: no
• regular inputs:
  - port 1 : size [-1,1] / type 1
  - port 2 : size [-1,1] / type 1
  
• regular outputs:
  - port 1 : size [-1,1] / type 1
  
• number/sizes of activation inputs: 0
• number/sizes of activation outputs: 0
• continuous-time state: no
• discrete-time state: no
• object discrete-time state: no
• name of computational function: logicalop
