Record the time evolution of a probe in a field

P = PROBE(F, X0, Y0), where F is an array of scalar fields, returns the
time series of a probe located at point (X0, Y0), specified in physical
units (eg., in mm). P is an array of size LENGTH(F).
[UX, UY] = PROBE(F, X0, Y0) or [UX, UY, UZ] = PROBE(F, X0, Y0) does
the same for a 2-component or a 3-component array of vector fields.
The value of the field at the location of the probe is interpolated
using Matlab's function INTERP2.

**Example**
v = loadvec('*.vc7');
[ux, uy] = **probef**(v, 20, 30);
t = 1:length(v);
plot(t, ux, 'b', t, uy, 'r');
xlabel('time t');
