title: Given a feature vector, how to find whether my data points are linearly separable
body: <p>I have a feature vector in matrix notation, and I have data points in 2D plane. How to find whether my data points are linearly separable with that feature vector? </p>
  
  <p>One can check whether there exists a line divides the data points into two. If there isn't a line, how to check for linear separability in higher dimensions?   </p>
