body: <p>i have question related to linespace  ,as   definition of linespace from matlab tutorials,it is function which  generates  linearly spaced points,but  what does means  linearly spaced points?for example following code linspace(5,10,4) Generates 4 linearly spaced points between 5 and 10.so it means that between  these posint there exist  linear  relationship?like</p>
  
  <pre><code>y=a*x+b?
  </code></pre>
  
  <p>because if it is  equally spaced points ,then it would be</p>
