title: Is there a function for solving xA=b in opencv?
body: <p>I know the function <code>solve</code> can solve <code>Ax=b</code>. But I want a function to solve xA=b for x?
  Is there some function available?</p>
  
  <p>By the way It should work like <a href="http://www.mathworks.cn/cn/help/matlab/ref/mrdivide.html" rel="nofollow">mrdivide</a> of Matlab:</p>
  
  <pre><code>x = B/A solves the system of linear equations x*A = B for x. The matrices A and B must contain the same number of columns. MATLAB® displays a warning message if A is badly scaled or nearly singular, but performs the calculation regardless.
  
  If A is a scalar, then B/A is equivalent to B./A.
  
  If A is a square n-by-n matrix and B is a matrix with n columns, then x = B/A is a solution to the equation x*A = B, if it exists.
  
  If A is a rectangular m-by-n matrix with m ~= n, and B is a matrix with n columns, then x = B/A returns a least-squares solution of the system of equations x*A = B.
