INTRP2BLK_f

2D interpolation

Block Screenshot

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.
