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

The output of this block is a function of the input obtained by linear
interpolation. This block has a single scalar input and a single
scalar output port. The coord. and coord. give respectively the
coordinate and the coordinate of the data points to be interpolated.

*The parameter vectors should be sorted (strictly increasing).*



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






+ **X coord.** A vector (strictly increasing). Properties : Type 'vec'
  of size -1
+ **Y coord.** A vector (same size as **X** coord). 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**
+ **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:** intrpl




Example
~~~~~~~

The following example translate the sinus input signal to a different
range and cut part of it. `Open this example in Xcos.`_
