setinterpmethod - Set default interpolation method for timeseries object

Syntax

ts = setinterpmethod(ts,Method)
ts = setinterpmethod(ts,FHandle)
ts = setinterpmethod(ts,InterpObj),

Description

ts = setinterpmethod(ts,Method) sets the default interpolation method for timeseries object ts, where Method is a string. Method in ts. Method is either 'linear' or 'zoh' (zero-order hold). For example:

ts = timeseries(rand(100,1),1:100);
ts = setinterpmethod(ts,'zoh');

ts = setinterpmethod(ts,FHandle) sets the default interpolation method for timeseries object ts, where FHandle is a function handle to the interpolation method defined by the function handle FHandle. For example:

ts = timeseries(rand(100,1),1:100);
myFuncHandle = @(new_Time,Time,Data)...
               interp1(Time,Data,new_Time,...
                       'linear','extrap');
ts = setinterpmethod(ts,myFuncHandle);
ts = resample(ts,[-5:0.1:10]);
plot(ts);

Note   For FHandle, you must use three input arguments. The order of input arguments must be new_Time, Time, and Data. The single output argument must be the interpolated data only.

ts = setinterpmethod(ts,InterpObj), where InterpObj is a tsdata.interpolation object that directly replaces the interpolation object stored in ts. For example:

ts = timeseries(rand(100,1),1:100);
myFuncHandle = @(new_Time,Time,Data)...
               interp1(Time,Data,new_Time,...
                       'linear','extrap');
myInterpObj = tsdata.interpolation(myFuncHandle);
ts = setinterpmethod(ts,myInterpObj);

This method is case sensitive.
