.SH NAME
INTRP2BLK_f - Scicos 2D linear interpolation block
.SH DIALOGUE PARAMETERS
.TP 20
X coord.
: an n-vector (strictly increasing)
.TP
Y coord.
: an m-vector (strictly increasing)
.TP
Z values
: an mxn matrix
.SH 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.
