判断下列方阵是否可对角化，是否为正定二次型（顺序主子式判断法、特征值判别法）(using MATLAB to determine if a the matrix is diagonalizable，if the real vector space is definite quadratic)

三阶龙格库塔，四阶龙格库塔程序，程序完善，通用性强！(The third order runge kutta, fourth order runge kutta procedures, process improvement, strong commonality. )

32个脉冲调制的线性调频连续波发射信号，单目标回波信号中加入了距离时延与多普勒频移信息。数字下变频后再进行脉压与MTD处理从而检测出距离与速度信息。(Chirp 32 pulse-modulated continuous wave transmit signals, a single target echo signal from the delay and added to the Doppler shift information. MTD frequency pulse pressure and then be processed to detect the distance and speed of digital information down.)
