Problems with function frestimate

Hi,

I also have problems with this function. I use the frestimate function as follows:

logdata = logsout{1}.Values;
sys_estim = frestimate(logdata,simu.w,'rad/s');
size(sys_estim)

and I get the following error:

Index exceeds the number of array elements (8).
Error in freblkData2Frd (line 80)
            uThisFreq = uts.Data(beginFreqPoints(ct):endEstimationPoints(ct));
Error in frestimate (line 78)
        varargout{1} = freblkData2Frd(data,w,units);
Error in Auswertung_Simulink_Stromregelung_o_par (line 38)
sys_estim = frestimate(logdata,simu.w,'rad/s');

I analyze my model for 10 frequencies.

But when I look in the function freblkData2Frd, I noticed that

nw 10 is (according to the number of frequencies)

but the arrays "startEstimationPoints", "endEstimationPoints" and "beginFreqPoints"

%% find start, end and samples for each frequency
    startEstimationPoints = find(diff(rts.Data)>0);
    endEstimationPoints = find(diff(rts.Data)<0);
    beginFreqPoints = [0;endEstimationPoints(1:end-1)] + 1;
    sampsPerPeriod = round(2*pi/Ts./w);

only have 9 elements.

But I don't know why they have only 9 elements.

For the analysis I use the "FrequencyResponseEstimator" block in Simulink. The simulation time is longer than the necessary time given by the block.

What is the cause of this problem?

Thanks a lot!
