This is the interpolation world...
AFAIK, there is no equivalent to griddata() in Scilab (core)

According to its help page, linear_interpn() takes poles on a grid
to interpolate on scattered points, but not the reverse, whereas
original data from Nobuyuki Hosomi are scattered.

Maybe a linear solution could be found in a Scilab external package ?
