MATLAB: Implementing dot between functions

simulink

i have to call the function adaptfilt.lms to matlab function block , but I don't know how to implement the dot between adaptfilt and lms standalone functions….thanks.

The dot between adaptfilt and lms is actually to depict that lms is a method that belongs to the adaptfilt class (the dot as in other languages is used as a separator between package, class and method names). For example, you can run:

>> which adaptfilt.lms

To see where the definition is located.

So you can directly use the adaptfilt.lms as described here.

... Continuation. Three or more periods at the end of a line continue 
      the current command or function call onto the next line. Three or 
      more periods before the end of a line cause MATLAB to ignore the 
      remaining text on the current line and continue the command or 
      function call onto the next line. This effectively makes a comment 
      out of anything on the current line that follows the periods.

MATLAB: How to use spectrum analyzer object to show a signal waveform

You can set FrequencyResolutionMethod to 'Window length' to manually adjust the length of signal used to compute the spectrum, e.g.,

Fs = 2500; 
Sineobject1 = dsp.SineWave('SamplesPerFrame',1024,'SampleRate',Fs,'Frequency',100); 
Sineobject2 = dsp.SineWave('SamplesPerFrame',1024,'SampleRate',Fs,'Frequency',1000); 
SA = dsp.SpectrumAnalyzer('SampleRate',Fs,'NumInputPorts',2,'PlotAsTwoSidedSpectrum',... 
    false,'ChannelNames',{'SinewaveInput','NotchOutput'},'ShowLegend',true,...
    'FrequencyResolutionMethod','WindowLength');
step(SA,step(Sineobject1),step(Sineobject2))
