Matrix” and “vector” are two important terms that you see often in 3D graphics programming literature(在3D图形学里,矩阵和向量是非常重要的东西). When dealing with these quantities, you also see the term “scalar.”(当处理这些数据的时候,你经常还会看到标量,一个标量就是一个表达长度的数字或者...
Part1 - 基本概念 General Concepts and Notation 向量空间(Vector space): 描述: Rn - vector space of n dimensional column vectors 例: a∈Rn⇔a=[a1..an] 理解:seniusen:线性代数之——向量空间加(Addition, Rm×n+Rm×n→Rm×n):
Vector3d v(1,2,3); Vector3d w(1,0,0); std::cout<<"-v + w - v =\n"<< -v + w - v <<std::endl; } Output: a + b =3548a- b = -1-120Doing a+=b; Now a=3548-v + w - v = -1-4-6 乘法运算: #include <iostream>#include<Eigen/Dense>usingnamespaceEigen;intmain...
The control of a three phase AC-AC matrix converter with sinusoidal input and output waveforms and unity power factor at the input side is presented. The control strategy has been developed utilising the space vector modulation technique. This approach has the advantage of an immediate comprehension...
This paper analyzed the topology evolution from conventional matrix converter(CMC) to two-stage matrix converter(TSMC) and verified that they have the same switching functions and transform function. However, the space vector modulation for TSMC is different from that CMC adopted for their different ...
Improved Space Vector Modulation Strategy for AC-DC Matrix Converters In this paper, an approach to reduce the common-mode voltage and to eliminate narrow pulse for implemented AC-DC matrix converters is presented. An improve... Xiao,Liu,Qingfan,... - 《Journal of Power Electronics》 被引量...

2.3.1 Matrix-Vector Multiplications Multiplication of Ĥ by trial vectors is required by diagonalization procedures that are appropriate for large matrices. Storage of the 2hp-2hp and 2ph-2ph blocks in memory [9, 32] or on external disks is impractical here, especially for low-symmetry molecul...
Two Matlab Simulation models: a simple model and a complex one, for the matrix converters with space-vector modulation are presented. In the simple model, switch matrix is composed of nine ideal switches. The simple model can be used to verify the improvement of the space-vector modulation str...
