   Here is our first function to inverse transform matrix without scaling (always unit scale).

   // Requires this matrix to be transform matrix, NoScale version requires this matrix be of scale 1
   inline Matrix4 GetTransformInverseNoScale(const Matrix4& inM)

  This is column major area. The first two functions for transform matrix is exactly the same in column major. Here is the general matrix inverse and helper functions:

  ----
  // for column major matrix
  // we use __m128 to represent 2x2 matrix as A = | A0  A2 |
  
negative.code: 
  Here’s the code for these three functions:
  
  [source, C/C++]
  ----
  // for row major matrix
  // we use __m128 to represent 2x2 matrix as A = | A0  A1 |
