RF Toolbox analyze function does not return properly sized array of S-parameters

My problem is the following:

When I run the simple example available from the Mathwork website here:

http://www.mathworks.com/help/toolbox/rf/rfckt.delay.analyzedresult.html

which is:

del = rfckt.delay; analyze(del,[1e9,2e9,3e9]); del.AnalyzedResult

The value returned in "AnalyzedResult" accurately holds the number of frequencies in del.AnalyzedResult.Freq as specified by "[1e9,2e9,3e9]" however, the S-parameter matrix appears to have been calculated for only one frequency. That is

size(del.AnalyzedResults.S_parameters) = [2 2]

when its size should be [2 2 3], there should be a 2x2 matrix for each frequency analyzed. Am I misinterpreting the data type or is this a bug in the analyze method? For now I can get around this by calculating the S-parameters myself but I'd like to get some closure to this quandary
