Gridding - Matlab to Octave

[Lester Anderson]

Hello,

I have come across a bit of code I am trying to get to run in Octave,
but found the function TriScatteredInterp:
...
[ XI, YI ] = meshgrid( tx, ty );
F = TriScatteredInterp( topo( :, x_maxi ), topo( :, y_maxi ), topo( :,
z_maxi ), 'linear' );
inptopo = F( XI, YI );[ M, N ] = size( inptopo );
...

Is there an equivalent function in Octave? I am wondering if
griddata() is correct.

Cheers
Lester
