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 X(i) and Y(i) give respectively the X coordinate and the Y coordinate of the i-th data point to be interpolated and Z(Y(i),X(i)) 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 m,n 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
