Thanks. I'll remember that in future.

They are vectors of real measurements with a lot of noise.
Consequently, k^4 * g''(k*t) - f''(t) = 0 is an ideal situation that is
only an approximation in practice. k is constant with respect to t.
However f(t) and g(t) will need to be measured across t in order to
estimate k. It may be a type of vector correlation problem.

Many thanks for your reply,
Peter.
