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