Tcl-nap version 6.2 on Ubuntu Linux:

All attempts to use the command scattered2grid result in errors, including copying and pasting the example from section 10.5.20 of the users guide into the interpreter. E.g.:

% nap "z = scattered2grid({{2 2 0}{6 4 0}{2 4 4}{4 5 3}}, 2 .. 5, 2 .. 6)"

abc = solve_linear(A, xyz(j,2))
^

abc = solve_linear(A, xyz(j,2))

Nap_SolveLinear: Error calling linsys_F64
abc = solve_linear(A, xyz(j,2))
