title: Call MATLAB APIs in C/C++
body: <p>I just heard from somewhere that for numerical computation, "MATLAB does offer some user-friendly APIs. If you call these APIs in your C/C++ code, you can speed up computation dramatically."</p>
  
  <p>But I did not find such information in MATLAB documents like <a href="http://www.mathworks.com/support/tech-notes/1600/1622.html" rel="nofollow noreferrer">http://www.mathworks.com/support/tech-notes/1600/1622.html</a> and <a href="http://www.mathworks.com/access/helpdesk/help/techdoc/matlab_external/bp_kqh7.html" rel="nofollow noreferrer">http://www.mathworks.com/access/helpdesk/help/techdoc/matlab_external/bp_kqh7.html</a>. All I learned from these websites is that MATLAB can be called in C and C++ by Matlab engine or by compiling M-files into libraries by mcc. They don't mention any built-in numerical MATLAB APIs that can be called in C/C++.</p>
  
  <p>Can someone please clarify?</p>
  
  <p>Thanks and regards!</p>
