c++mathmatrixbinarytranspose 11 我在C++中有二进制矩阵,使用8位值的向量表示。 例如,以下矩阵: I have binary matrices in C++ that I repesent with a vector of 8-bit values. For example, the following matrix: 1 0 1 0 1 0 1 0 1 1 0 0 1 1 0 0 0 1 1 1 1 表示为: const uint...
图书《3D 数学基础:图形与游戏开发》 Fletcher Dumn ,Lan Parberry;史银雪,陈洪,王荣静译,背景递归开元教育科技有限公司审校;是出版于 2005年,英文原版,出版的就更早了,所以有可能是Eigen引用了书中提到空间变换的代码,比如 MathUtil.h MathUtil.cpp; Eigen库中所有矩阵和向量都是Matrix模板类对象,Vector是1种特...
If we take a closer look in the scalar multiplication process, we can see that we can calculate the whole vector at once: In the scalar code, Vec.x is multiplied with the first four elements of the matrix. Those four elements are represented as the first line of the matrix, and are ...

代码在:http://svn.r-project.org/R/trunk/src/nmath/log1p.c 有兴趣的可以自己去看。代码比较多就不贴在这里了。 expm1(x) expm1(x) = exp(x) - 1 当x很小的时候,exp(x) 很接近 1。两个很接近的数字相减同样会导致有效数字急剧减少。比如当 x = 1e-15 时。Exp(x)-1 = 1.00000000000e-15...
