Method ssm/cpsdForIndependentInputs

  CPSDFORINDEPENDENTINPUTS computes the output theoretical CPSD shape with given inputs.
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
 
  DESCRIPTION: cpsdForIndependentInputs computes the output theoretical
               CPSD or PSD shape for given input shapes.
               It returns summed and individual contributions and takes
               input vectors of objects (instead of square matrices)
 
  CALL:        [mat_outSum, mat_out] = PSD(sys, pl)
 
  INPUTS:
                sys - (array of) ssm object
 
  OUTPUTS:
               mat_outSum - contains specified returned aos, noise is
                            summed over all the specified input noises
               mat_out    - contains specified returned aos

reorganize
VARIANCE VARIABLE NAMES	{} [0x0]	none	A cell-array of strings specifying the desired input variable names.
PSD VARIABLE NAMES	{} [0x0]	none	A cell-array of strings specifying the desired input variable names.
PZMODEL VARIABLE NAMES	{} [0x0]	none	A cell-array of strings of the desired input variable names.
AOS VARIABLE NAMES	{} [0x0]	none	A cell-array of input defined with AOs spectrums.
RETURN STATES	{} [0x0]	none	A cell-array of names of state ports to return.
RETURN OUTPUTS, OUTPUTS	{} [0x0]	none	A cell-array of output ports to return.
cpsdForIndependentInputs
VARIANCE	[]	none	The variance vector of this noise between input ports for the time-discrete noise model.
PSD	[]	none	The one sided psd vector of the white noise between input ports.
AOS	[]	none	A vector of input PSD AOs, The spectrum of this noise between input ports for the time-continuous noise model.
PZMODELS	[]	none	vector of noise shape filters for the different corresponding inputs.
REORGANIZE	1	1 0	When set to 0, this means the ssm does not need be modified to match the requested i/o. Faster but dangerous!
F2	[]	none	The maximum frequency. Default is Nyquist or 1Hz.
F1	[]	none	The minimum frequency. Default is f2*1e-5.
NF	200	none	The number of frequency bins. Frequencies are scale logarithmically
DIAGONAL ONLY	1	1 0	Set to true if you want the PSD instead of the CPSD
