Details:

If I try to use in Octave the griddata function as:


>> x=rand(10,1);
>> y=rand(10,1);
>> z=rand(10,1);
>> xi=rand(5,1);
>> yi=rand(5,1);
>> griddata(x,y,z,xi,yi)


I obtain an error:


error: surface: rows (Z) must be the same as length (Y) and columns (Z) must
be the same as length (X)
error: called from
    surface>__surface__ at line 128 column 11
    surface at line 60 column 19
    mesh at line 76 column 12
    griddata at line 142 column 5


But in Matlab the function works and the output is a vector with the same
dimensions as xi and yi
