help i like the new DSP Spectum but for the life of me can't get my tones of wavefoms to display

hi

Ok so I'm confused, I have looked into the examples but would like a simple Simulink that lets me select a *.mat file and a variable in it to be displayed on the spectrum analyzer...

Generally my files generated by different programs are complex (I/Q) data stored in .mat files..

I tried but this does not work, if 0 %//zap hsb = dsp.SpectrumAnalyzer; hsb.SampleRate = Fs; hsb.SpectralAverages = 1; hsb.PlotAsTwoSidedSpectrum = false; hsb.FrequencyResolutionMethod = 'RBW'; hsb.PowerUnits = 'dBm'; hsb.PlotMaxHoldTrace=true; contF = inputdlg('enter "p" For Power Spectrum','Input',1,{'p'}); if char(contF) == 'p' hsb.SpectrumType = 'power'; else hsb.SpectrumType = 'Spectrogram'; end %hsb.Position = [749 227 976 721]; show(hsb); fSz = 6000; % Frame size %wavB1_fs200a = real(CplxWaveIn)'; wavB1_fs200a = abs(CplxWaveIn)'; filename = [tempname '.mat']; % Create variable name save(filename,'wavB1_fs200a','-v7.3'); % Write to MAT file contFlag = 'c'; while contFlag == 'c' H = dsp.MatFileReader(filename,'VariableName','wavB1_fs200a','SamplesPerFrame', fSz); while ~isDone(H) % Stream data into MATLAB y1 = step(H); if max(y1) ~= 0 step(hsb,y1); end end end contFlag = input('enter "c" to loop again: ','s'); end

also this simulink it does not work;.
