It is not a correct least squares method, therefore the results are not as accurate as they could be and it is not generally applicable. Many other methods have been invented, but most of them suffer from the same flaws as the sin2ψ method. With the matrix method we could get rid of...
Introduction A major application of linear algebra is to solving systems of linear equations. This lecture presents three ways of thinking about these systems. The “row method” focuses on the individual equations, the “column method” focuses on combining the columns, and the “matrix method” ...

The matrix exponential is a very important subclass of control theory. In control theory it is needed to evaluate matrix exponential. In classical methods we calculate the eigenvalues of the matrix, but that the problem can be complicated if the eigenvalues are not easy to calculate. In this ...
The Eisenhower Matrix is a time management tool for prioritizing tasks. It is also known as the Urgent/Important Matrix, Time Management Matrix and the Eisenhower Method. The Eisenhower Matrix gets its name from the 34th president of the United States, Dwight D. Eisenhower, who was quoted sayin...
It provides examples, codes, and exercises to connect the theory of the Finite Element Method directly to the applications. The reader will learn how to assemble the stiffness matrix K and solve the finite element equations KU=F. Discontinuous Galerkin methods with a numerical flux function are ...
The preconditioners take advantage of the hierarchical struture of the matrices in these methods and the fact that most of the matrix does not change when simulating for example, the evolution of interfaces and fractures. The performance of the conjugate gradient method with the proposed ...
2. No matrix inversions Disadvantages: 1. Needs many iterations until convergence in certain configurations 2. Unpredictable joint configurations 3. Non conservative 下面以V-rep中官方自带的例子(在文件夹scenes/ik_fk_simple_examples中)为基础进行修改,添加代码手动实现运动学逆解的求解。为了实现同样的功能先...
