matlab 基础上通过最小二乘法进行模态参数识别，得出固有频率，振型，阻尼比，图形(by the least squares method matlab based on the identification of modal parameters obtained natural frequency, mode shape, damping ratio, graphics)

[的X，Y和Z] = cylinder2（的x，Y，Z轴，俄，氮，氧） 向量X，Y，Z轴定义圆柱面中心线 和矢量r定义圆柱面半径，并已 为的x，y，z的长度相同 N是周围围点的数量。默认值 为N= 100。 矩阵Ø 定义了准线（圈）椭圆圆柱 表面。其内容以0和1之间的值，并适用于 小学和中学的准线轴。值的defeault Ø =的（长（x），2）。 矩阵X，Y，Z轴确定圆柱面，冲浪（的X，Y，Z）的显示器 圆柱面。( [X,Y,Z]=cylinder2(x,y,z,r,N,o) Vectors x, y, z define the central line of cylindrical surface and vector r defines the radius of cylindrical surface, and has the same length as x, y, z. N is the number of points around the circumference. The default value is N = 100. Matrix o defines ovality of the directrix (circle) of cylindrical surface. Its elements take values between 0 and 1 and apply to the primary and secondary axis of directrix. The defeault values are o=ones(length(x),2). Matrices X, Y, Z define the cylindrical surface, surf(X,Y,Z) displays the cylindrical surface. )
