描述
hom_mat2d_determinanthom_mat2d_determinantHomMat2dDeterminantHomMat2dDeterminantHomMat2dDeterminanthom_mat2d_determinant computes the determinant of the
homogeneous 2D transformation matrix given by HomMat2DHomMat2DHomMat2DHomMat2DhomMat2Dhom_mat_2d and
returns it in DeterminantDeterminantDeterminantDeterminantdeterminantdeterminant。
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
