关于含有符号k的隐函数方程：(x-2y)(4x-y)(k+(x-y))+2y(x-y)(k-3x)=0,以x为横坐标，y为纵坐标，且都以k为单位，横纵范围均为0k——1k, 用matlab或者maple作图

1. Explore(plots[implicitplot]((x-2*y)*(4*x-y)*(k+x-y)+2*y*(x-y)*(k-3*x),x=0..10*k,y=0..10*k,gridrefine=5,gridlines));

skip x和y,gridlines,gridrefine，k从1到10；

1. plots[display](seq(plots[implicitplot]((x-2*y)*(4*x-y)*(k+(x-y))+2*y*(x-y)*(k-3*x),x=0..10*k,y=0..10*k,gridrefine=5,gridlines),k=1..10,0.1), insequence = true);

以上两个命令均可
