Description
~~~~~~~~~~~

The Ramp block generates a signal that starts at a specified **Start
Time** and **Initial Value** and increases by a specified rate (
**Slope** parameter). The output signal is defined by the following
equation:





where * `t 0 `* is the **Start Time**, * `s 0 `* the **Initial Value**
and * `k`* the **Slope**.



Data types
~~~~~~~~~~


+ Output: scalar double.




Dialog box
~~~~~~~~~~






+ **Slope** Scalar. The rate of change of the generated signal.
  Properties : Type 'vec' of size 1.
+ **Start Time** Scalar. The time at which the signal begins to
  increase. Properties : Type 'vec' of size 1.
+ **Initial Value** Scalar. The initial value of the signal.
  Properties : Type 'vec' of size 1.




Default properties
~~~~~~~~~~~~~~~~~~


+ **always active:** yes
+ **direct-feedthrough:** no
+ **zero-crossing:** yes
+ **mode:** yes
+ **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:** ramp




Example
~~~~~~~

This diagram shows the use of RAMP block to obtain the response to a
ramp signal of a first order's system defined by a transfer function.
