polyfit demo program with noise added in(polyfit)

根据多行三列的实验数据（x,y,signal)作出contourf图。其中x,y为二位空间位置（或其他概念的二维），signal为在该位置的信号。此代码先将数据按位置不同求平均，再将signal按照其对应的x,y分配到二位矩阵内。最后作图。编这个代码的初衷是为了制作大脑hippocampus区域place cell 活动性的contour 图。(it s a code i made for plotting a contour graph of experimental data (x,y,signal). The data should be n*3 arrays which cannot be plot into contour directly. In fact, it can subplot 6*6 graphs or more, but speed might be slow..... especially, when you want more detailed graphs.)

用MATLAB编写的几个简单的GUI案例(Prepared using MATLAB few simple GUI Case)

the attached all programs are based on error control coding for ex. LBC, Convolition, RS code etc. all programs are generalized means for any size input or any type of circuit respectively. the all programs are tested on matlab 2012

[自動控制] Routh-Hankel matrix數值計算工具，輸入System Function後，程式會計算Hankel singular values and vectors、Schmidt pairs等值。詳情請見英文描述。(<<singular values and vectors>> [R_G,Sigma,U,V,Us,Vs]=HANKEL3(G) computes the Routh-Hankel matrix, the Hankel singular values and vectors, the Schmidt pairs of a given proper stable system G (created with either TF, ZPK, SS, or FRD).|| Output "R_G" is the Routh-Hankel matrix. || Output "Sigma" is a matrix whose elements on the diagonal are the Hankel singular values of the given system. || Output "U" is a matrix, the ith column of which is the left singular vector corresponding to the ith singular value. || Output "V" is a matrix, the ith column of which is the right singular vector corresponding to the ith singular value. || Output "Us" and "Vs" provides the Schmidt pairs. The ith elements of Us and Vs form the Schmidt pair corresponding the ith Hankel singular value. )
