warp.quat\_from\_matrix
=======================

.. function:: warp._src.lang.quat_from_matrix(mat: Matrix[Float,Literal[3],Literal[3]]) -> Quaternion[Float]

   .. hlist::
      :columns: 8

      * Kernel
      * Differentiable

   Construct a quaternion from a matrix.
   
   If the matrix is not a pure rotation, but for example includes scaling or skewing, the result is undefined.

   :noindex:

   .. hlist::
      :columns: 8

      * Kernel
      * Differentiable

   Construct a quaternion from a matrix.
   
   If the top-left 3x3 block of the matrix is not a pure rotation, but for example includes scaling or skewing, the result is undefined.
