title: PyTorch mapping operators to functions
body: <p>What are all the PyTorch operators, and what are their function equivalents?</p>
  
  <p>Eg, is <code>a @ b</code> equivalent to <code>a.mm(b)</code> or <code>a.matmul(b)</code>?</p>
  
  <p>I'm after a canonical listing of operator -> function mappings.</p>
  
  <p>I'd be happy to be given a PyTorch documentation link as an answer - my googlefu couldn't track it down.</p>
