A numerical application of the modus tollens rule of classical logic is described and is shown to permit the calculation of off-diagonal matrix elements by using a small basis set of implicit wavefunctions. The success of the calculation is discussed in terms of the most simple form of the ...

We present a powerful semiclassical expression to evaluate off-diagonal matrix elements of the evolution operator between quantum states constructed in the neighborhood of unstable short periodic orbits, which is valid up to the Heisenberg time. The expression is much easier to evaluate than the Van ...

Some problems of computing B-spline curve s control points are equivalent to those of solving a linear equation in which is a tri-diagonal matrix. 三次B样条曲线在实际工程中被广泛应用,反求三次B样条曲线控制顶点的问题在很多情况下可归结为求解一个系数矩阵为三对角矩阵的方程组Ax=s,一般采用追赶法...
First, ODsymNMF is theoretically much more sound as there always exists an exact factorization of size at most $icefrac{n(n-1)}{2}$ where $n$ is the dimension of the input matrix. Second, it makes more sense in practice as diagonal entries of the input matrix typically correspond to ...
