Description

This block is an integrator. The output is the integral of the input.

Dialog box

• Initial Condition
  A vector/scalar initial conditions.
  With that parameter, one can define the datatype of the input/output. It can be a real or a complex type.
  Properties : Type 'mat' of size [-1,-1].

• With re-initialization
  To reset its state to the specified initial condition based on an external signal select 1.
  Properties : Type 'vec' of size 1.

• With saturation
  If selected, limits the states to a value between the Lower saturation limit and Upper saturation limit parameters.
  Properties : Type 'vec' of size 1.

• Upper limit
  The upper limit for the integral.
  Properties : Type 'mat' of size [-1,-1].

• Lower limit
  The lower limit for the integral.
  Properties : Type 'mat' of size [-1,-1].

Default properties

• always active: yes
• direct-feedthrough: no
• zero-crossing: no
• mode: no
• regular inputs:
  - port 1 : 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: yes
• discrete-time state: no
• object discrete-time state: no
• name of computational function: integral_func
