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 X coord. and Y coord. give respectively the X coordinate and the Y coordinate of the data points to be interpolated. X coord must be 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
