pi
说明： 一个用于求圆周率pi的matlab算法。题目背景：取一长面积为1平方米的正方形白纸，在白纸的内部画一个直径为1米的圆，如下图所示。此圆恰好与正方形的四条边分别切于一点，它的面积是
pi*（1/2）^2 =pi/4 ,然后，你可以抓一大把芝麻，一粒一粒地随便地扔到白纸上。在你扔麦子的过程中可以请一位朋友帮助记录：一共扔了几次？有几次是扔在圆里面？
实验结束后，你只须用“芝麻落在圆里的次数”除以“一共扔的次数”得到的结果就是圆的面积。则pi就是“圆的面积*4”了
当然，你扔的次数越多，结果就越精确！()

finite_ridgelet_transform_toolbox
The ridgelet transform (Candµ es and Donoho,
1999) was introduced as a sparse expansion for functions on continuous spaces that are smooth away discontinuities along lines. Our construction uses the ¯ finite Radon transform
(FRAT) as a building block. Taking the one-dimensional wavelet transform
on the projections of the FRAT in a special way results in the ¯ finite ridgelet transform (FRIT), which is invertible,non-redundant, and computed via fast algorithms.

本实验语音库为免费的柏林情感语音库，其采样频率为16KHZ，16bit量化。该语音库共有500 句情感语音信号，分别由十名专业演员(5 男，5 女)在不同情感状态下（高兴、愤怒、平静、悲伤、害怕、厌烦、憎恨）朗读十句不同文本的德语组成。本实验选取其中的部分情感（高兴、愤怒、悲伤）加以识别。仿真实验环境为MATLAB7.0。
实验选取的情感特征为短时平均能量、短时平均幅度、基频和短时过零率。为了降低不同人在表达不同情感时的个人差异造成的影响，本文实验过程中将提取的情感特征进行归一化处理。归一化采取将同一个人的三种情感语音信号的情感特征放在一起归一化处理，并将归一化后的情感特征作为KNN分类器的训练样本和测试样本。
该实验使用了传统的KNN算法和改进算法两种识别方式，通过实验结果对比了各自的特点。
(This experiment YuYinKu for free Berlin YuYinKu emotion, the sampling frequency for 16 KHZ, 16 bit quantification. The YuYinKu 500 words of emotional speech signal, respectively by ten professional actors (5 male, five female) in different emotional state (happy, anger, sadness, fear, calm, bored, hate) read ten sentences in different text of the German. This experiment selection of part of the emotions (joy, anger, sadness) is recognized. The simulation experiment environment for MATLAB7.0.
The selection of emotional characteristics for short-term average energy, short-term average amplitude, frequency, and the short zero rate. In order to reduce the different people in different emotional expression of the impact of individual differences, the experiment process will extract emotional characteristics is normalized. The normalized will take the same three kind of emotional speech signal emotional features normalized put together, and after the normalized the emotional characteristics)
