To solve the Fredholm integral equations of the second kind, a new notion of the least-squares orthogonal polyno- mials of function-valued Pade-type approximation is introduced. On the basis of the error formula, the least-squares function: valued Pad&type approximation is constructed. Their existence and uniqueness are studied. A recursive computation formula of the least-squares function-valued Padetype approximation is given. In the end, an example is given to show that the method is effective and stable.  相似文献

We derive necessary and sufficient conditions for the existence and an expression of the (anti)reflexive solution with respect to the nontrivial generalized reflection matrix P to the system of complex matrix equations AX = B and XC = D. The explicit solutions of the approximation problem min x∈Ф ||X - E||F was given, where E is a given complex matrix and Ф is the set of all reflexive (or antireflexive) solutions of the system mentioned above, and ||·|| is the Frobenius norm. Furthermore, it was pointed that some results in a recent paper are special cases of this paper.  相似文献

INTRODUCTION The inverse kinematics problem (IKP) for a ro- botic manipulator involves obtaining the required manipulator joint values for a given desired end-point position and orientation. It is usually complex due to lack of a unique solution and closed-form direct ex- pression for the inverse kinematics mapping. The forward kinematics problem (FKP) is to find the po- sition and orientation of the end-effector based on given joint values which can be easily obtained by analyzing the …  相似文献

先秦货殖思想家中,对货殖“取予”思想有独到见解的,首推白圭,其“取予以时”思想最具代表性。老子的“欲取固与”思想,孔子的“惠而不费”思想,管子的“形予实取”思想,也体现了“先予后取,以予为取”的精髓。先秦贷殖家白圭及老子、孔子、管子的“取予”思想,独具中国特色,具有重大的理论价值和现实意义。  相似文献
