We have a function of 5 variables, f(a, b, c, d, e), that is given at regularly structured nodes: we are given the value
of f at f(a_i, b_j, c_k, d_l, e_m) for each a_i and each b_j and so on.

The output sought is then the multilinear interpolation of f at some arbitrary point.

I do not quite see what you mean by this, but I do not think so.
