matlab实现ofdm完整系统，包括qpsk调制，串并变换，ifft，同步等(ofdm in matlab)

串的一些基本运算，删除一段子串，置换，求s串中从start位置开始长度为len的子串等等(Some of the basic string operations, delete a substring, replacement, seeking s string starting from the start position of the sub-string of length len, etc.)

功能：对矩阵A的左上角的m阶对角块作QR变换：先用Givens变换作QR分解A=QR， 再作相似变换A:=Q AQ=RQ. 输入: n阶HessenbergA，其中A(m+1,m)=0,m>2. 输出: 变换后的Hessenberg形矩阵A. 2 用基本QR算法求实方阵的全部特征值.(Function: the upper left corner of the matrix A, diagonal blocks of order m to QR transformation: first, to make QR decomposition using Givens transformations A = QR, re-similarity transformation A: = Q' AQ = RQ. Input: n-order HessenbergA, where A (m+1, m) = 0, m> 2. Output: transformed Hessenberg form matrix A. 2 matrix with the basic QR algorithm for all the characteristics of the value of truth-seeking.)

Field Ⅱ超声成像代码，可以进行单个孔径成像和合成孔径成像、加权和不加权仿真。(The calculation of point spread functions is done by placing a point in front of the transducer and then sweeping the beam over the point. This gives the point spread function of the imaging system. Field II can make this calculation for a number of points simultaneously and thereby reveal the dynamic focusing properties of the imaging system. A point phantom has been made for this purpose. It consists of a number of point targets placed with a distance of 5 mm starting at 15 mm from the transducer surface)
