### Description

The output of this block is a function of the inputs obtained by bilinear interpolation. This block has two scalar inputs and a single scalar output. The and give respectively the coordinate and the coordinate of the -th data point to be interpolated and its value.

### Dialog box

- X coord.
  an n-vector (strictly increasing).
  Properties : Type 'vec' of size -1

- Y coord.
  an m-vector (strictly increasing).
  Properties : Type 'vec' of size -1

- Z values
  an matrix.
  Properties : Type 'mat' of size [-1,-1]

### Default properties

- always active: no
- direct-feedthrough: yes
- zero-crossing: no
- mode: no
- regular inputs:
  - port 1 : size [1,1] / type 1
  - port 2 : 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: intrp2
