power_3phsignaldq
A Discrete 3-Phase ProgrammableSource block is used to generate a 1 pu, 15 degrees positive sequence voltage. At t = 0.05 s the positive sequence voltage is increased to 1.5 pu. At t = 0.1 s an unbalance is introduced by adding a 0.3 pu negative sequence component with a phase of -30 degrees.
The magnitude and phase of the positive-sequence component is evaluated in two diiferent ways: 1) Sequence calculation of phasors using Fourier analysis and
2) abc to dq0 transformation.
Math Function and Trigonometric Function blocks are used to evaluate the magnitude and phase of the positive sequence from the d and q components:
V1 = sqrt(Vd^2 + Vq^2) , Phi1 = atan(Vq/Vd))

newton
这是一个用matlab编写的牛顿法源代码,比较简单的无约束方程。牛顿法是求非线性方程(组)零点的一种重要的迭代法,又称牛顿-拉弗森法或切线法。(This is a matlab source code written in Newton s method, relatively simple equation of the non-binding.
Newton s method is the pursuit of non-linear equation (group) zero is an important iterative method, also known as Newton- La Fusen law or tangent method.

Matlab
这是一本有关MATLAB的参考书,适合于使用MATLAB或正在打算使用MATLAB的读者。本书另辟蹊径可以借助或不借助MATLAB随带的文档资料让读者自学MATLAB。
作为编程语言和可视化工具,MATLAB具有丰富的一系列功能,可解决工程、科学计算和数学学科中许多问题。本书的基本目的是通过向读者展示如何有效地使用这些功能来帮助读者增强工作能力。由于MATLAB交互式的性质,书中内容以举例方式来描述。在读者阅读本书的同时, 这些例子可以通过运行MATLAB而再现。
(This is a reference book on MATLAB, suitable for the use of MATLAB or is intended to use MATLAB readers. Another way this book can make use of, or without the aid of MATLAB documentation that came with the reader learning MATLAB. As a programming language and visualization tools, MATLAB has a rich range of functions, solve engineering, scientific computing and mathematics disciplines, many problems. The basic purpose of this book by showing the reader how to effectively use these features to help readers enhance the ability to work. Since MATLAB interactive nature of the book by way of example to describe the content. The reader to read this book at the same time, these examples by running the MATLAB and reproduction.)
