Description: 提到 RPG （角色扮演游戏，Role Play Game），在座各位恐怕没有不熟悉的。从古老经典的 DOS 版《仙剑奇侠传》到新潮花哨的《轩辕剑》系列，无不以曲折优美的故事情节，美丽可人的主角，悦耳动情的背景音乐，震撼了每一个玩家的心灵。而说到 RPG，就不能不提 DirectX，因为 PC 上大部分的 RPG 都是用这个冬冬开发的。早在《轩辕剑叁外传——天之痕》推出的时候，我就曾想过用 DirectX 写一个自己的 RPG，自己来安排故事情节的发展，却总是因为这样或那样的事情，一直没有能够实现这个心愿。在耗费了宝贵的几年青春，搞定了诸如考试、恋爱、出国等琐碎杂事之后，我终于可以在这个 SARS 肆虐的时代，坐在陪伴了我整个大学生涯的电脑前，听着颓废而又声嘶力竭的不知名歌曲，写一些一直想写却没有写的东西。-mentioned RPG (role-playing game, Role Play Game) No, I am afraid you are not familiar with. From the old classic DOS version of "goods" to the garish hip "X-Men" series, all twists and turns to a beautiful story, beautiful girl, the protagonist, the emotionally pleasant background music, each one shook the player's minds. Talking about the RPG, one has to mention DirectX. because most of the PC RPG has been used in the development of the boys. Back in the "X-Men San rumor -- Tianzhigen" launched, I once thought of using DirectX write their own RPG, to arrange their own story of development, because it is a way or another things have not been able to achieve this aspiration. Wasting precious years of their youth, to get as examinations, love and leave the

Description: function Px = music(x,p,M)
MUSIC Frequency estimation using the MUSIC algorithm.
-----
USAGE Px=music(x,p,M)
The input sequence x is assumed to consist of p complex
exponentials in white noise. The frequencies of the
complex exponentials and the variance of the white noise
are estimated using the MUSIC algorithm.
x : input sequence
p : number of complex exponentials to find
M : number of noise eigenvectors to use
The frequency estimates are found from the peaks of the
pseudospectrum Px.-function Px = music(x,p,M)

Description: MUSIC estimates the frequency content of a signal or autocorrelation matrix using an eigenspace method. This method assumes that a signal, x(n), consists of p complex exponentials in the presence of Gaussian white noise. Given an M \times M autocorrelation matrix, \mathbf{R}_x, if the eigenvalues are sorted in decreasing order, the eigenvectors corresponding to the p largest eigenvalues (i.e. directions of largest variability) span the signal subspace. The remaining M-p eigenvectors span the orthogonal space, where there is only noise. Note that for M = p + 1, MUSIC is identical to Pisarenko harmonic decomposition. The general idea is to use averaging to improve the performance of the Pisarenko estimator.
