title: Finding closest (not equal) rows in two matrices matlab
body: <p>I have two matrices A(m X 3) and B(n X 3); where m >> n.</p>
  
  <p>Numbers in B have close or equal values to numbers in A.</p>
  
  <p>I want to search closest possible values from A to the values present in B in a way that at the end of search, A will reduced to (n X 3).</p>
  
  <p>There are two main issues:</p>
  
  <ol>
  <li>Only a complete row from A can be compared to a complete row in B, where numbers in each column of A and B are varying independently.</li>
  <li>Numbers in A and B may be as close as third place of decimal (e.g. 20.101 and 20.103) </li>
  </ol>
  
  <p>I hope I am clear in asking my question.
  Does anybody know about any function already present in matlab for this thing?</p>
