timeseries: ts = setinterpmethod (ts, name)

timeseries: ts = setinterpmethod (ts, fh)

timeseries: ts = setinterpmethod (ts, ip)

Set the interpolation method.

ts = setinterpmethod (ts, name) sets the method resample and synchronize use to name, 'linear' or 'zoh' (zero-order hold, keeping each value until the next sample), matched in any case and stored in lower case. MATLAB stores any name, 'cubic' included, and fails only on resampling; here another name is refused.

ts = setinterpmethod (ts, fh) sets a method evaluated by the function handle fh, called as MATLAB calls it: newData = fh (newTime, oldTime, oldData), with the times as columns and the data with time along its first dimension, so three-dimensional data is passed permuted.

ts = setinterpmethod (ts, ip) sets the method held by the tsdata.interpolation object ip.

The interpolation method says how the series behaves between samples, which resample and synchronize follow: 'linear' joins them, 'zoh' holds each value until the next sample.
