% DESCRIPTION: RESAMPLE resamples each time-series AO in the matrix.
%
% CALL:        out = resample(in,pl);
%
% Note: this is just a wrapper of ao/resample. Each AO in the matrix is passed
% to resample with the input plist. 
% 
% INPUTS:      in      -  input matrix objects 
%              pl      -  parameter list
%
% OUTPUTS:     out     -  output matrix objects
