此文件为四种空间DOA估计的MATLAB程序，包括：MUSIC, ROOTMUSIC，ESPRIT和MVDR四种方法，并带有相应的仿真图，便于比较其优缺点,很有用哦(MATLAB for DOA estimate : MUSIC, ROOTMUSI,ESPRIT and MVDR,the coresponding figures are acompanied to compare the advantages and disadwantages,they are useful)

music change speed中，jiasu.m是让一首音乐旋律速度加快播放，jiansu.m是让一首音乐旋律速度减慢播放，两个情况下都不改变音乐的基调。(Music change speed, jiasu.m is to allow a faster melodic playing, jiansu.m is to make a musical rhythm to slow down play, the two cases do not change the tone of music.)
