   Here’s the code for these three functions:
   
  -[source, c++]
  +[source, C/C++]
   ----
   // for row major matrix
   // we use __m128 to represent 2x2 matrix as A = | A0  A1 |
  
positive.code: 
  Now we have all pieces ready, here is our function for general 4x4 matrix inverse:
  
  [source, c++]
  ----
  // Inverse function is the same no matter column major or row major
  // this version treats it as row major
  
negative.code: 
  Here is our first function to inverse transform matrix without scaling (always unit scale).
  
  [source, C/C++]
  ----
  // Requires this matrix to be transform matrix, NoScale version requires this matrix be of scale 1
  inline Matrix4 GetTransformInverseNoScale(const Matrix4& inM)
