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 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
