IMAG overloads the imaginary operator for Analysis objects.
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
DESCRIPTION: IMAG overloads the imaginary operator for Analysis objects.
CALL: ao_out = imag(ao_in);
ao_out = imag(ao_in, pl);
POSSIBLE VALUES: ao_in = [ao2 ao3]
ao_in = ao_vector
ao_in = ao_matrix
PARAMETER LIST: <key> <value> <description>
tsdata fsdata xydata
'xdata' 't' 'f' 'x' compute the xdata
'ydata' 'x' 'xx' 'y' compute the ydata
The following call returns a parameter list object that contains the
default parameter values:
>> pl = imag(ao, 'Params')
