(Temporal) re-sampling of vector/scalar fields.
SF = resamplef(F,TINI,TFIN), where TINI is a vector of initial
times and TFIN a vector of final times, re-samples the structure array
of scalar or vector fields F from TINI to TFIN. This re-sampling is
based on a linear interpolation on the final times TFIN.
This function is useful if some data were acquired at a given
frequency, and one wants to resample them to another frequency which is
not a simple multiple of the initial frequency.
The input parameters must satisfy:
- LENGTH(F) == LENGTH(TINI)
- TINI must be increasing
- all values of TFIN must be between TINI(1) and TINI(end)
v = loadvec('*.vc7');
tini = 1:0.4:100; % if acquisition were performed with dt = 0.4 s
tfin = 1:0.5:100; % we want to convert it to dt = 0.5 s
sv = resamplef(v,tini,tfin);
