### 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
