title: Calculate Nyquist Frequency of signal from a data set
body: <p>I have a data set containing x (time) and y (concentration). Is it possible to calculate nyquist frequency from this ?</p>
  
  <p>From the below time series the y values are being generated by solving a system of ODE's.</p>
  
  <p>The time period of cycle is 24hrs (1440 min)</p>
  
  <pre><code>time=[0:0.05:1440]; %time in minutes 
  </code></pre>
  
  <p>Thanks </p>
