matlab中[X,Y,Z]=sphere(50); X1=4*X;Y1=4*Y;Z1=4*Z; surf(X,Y,Z)
matlab程序优化figure[x,y,z] = sphere;a=surf(x,y,z);% sphere cent
matlab中sphere函数 [X,Y,Z]=sphere(30); 其中30代表什么.
matlab中sphere函数 [X,Y,Z]=sphere(30); 其中30代表的是什么
(x+y-z)(x-y+z)=
1.设X ,Y,Z 成等差数列,代数式(X-Z)*(X-Z)+ 4(X-Y)(Z-Y)=
x=y/z=z/3,x+y+z =12,求2x+3y+4z是多少,
用MATLAB画出U=5x+4y+2z的图形条件为x+y+z=30;3x+y+z=50
X+Y+Z=?
方程组{4x-3y-3z=0,x-3y+z=0,(x.y.z不等于0),求x/z和y/z的值?
4x-3y-3z=0 x-3y+z=0 并且X Y Z不等于0 求x:z 和y:z的值
1.x+y+z=30,3x+y-z=50,x,y,z为非负数,求5x+4y+2z取值范围.
