(1)X,Y,Z是同维向量，绘制以X,Y,Z元素为x,y,z坐标
的三维曲线
(2)X,Y,Z是同维矩阵，则以X,Y,Z对应列元素为x,y,z
坐标分别绘制曲线，曲线的条数等于矩阵的列数。
(3)s，s1，s2的意义与二维情况相同。
(1) X, Y, Z is a vector with dimension, drawn to X, Y, Z elements x, y, z coordinates of the three-dimensional curve (2) X, Y, Z is a matrix with dimension, 则以 X, Y, Z corresponds to the column elements x, y, z coordinates of the drawn curve, the curve is equal to the number of bars the number of columns matrix. (3) s, s1, s2 of the meaning and the same two-dimensional case. (2010-04-09, MathCAD, 195KB, 下载14次)
