Description

hom_mat2d_determinanthom_mat2d_determinantHomMat2dDeterminantHomMat2dDeterminanthom_mat2d_determinant computes the determinant of the homogeneous 2D transformation matrix given by HomMat2DHomMat2DHomMat2DhomMat2Dhom_mat_2d and returns it in DeterminantDeterminantDeterminantdeterminantdeterminant.

Execution Information

  • Multithreading type: reentrant (runs in parallel with non-exclusive operators).
  • Multithreading scope: global (may be called from any thread).
  • Processed without parallelization.
