在matlab中绘制具有顶点A(6，-1,2)，B(-2,3，-4)，C(-3,1,5)的笛卡尔坐标系中的三维三角形

A = [6, -1, 2];
B = [-2, 3, -4];
C = [-3, 1, 5];

hold on;
plot3([A(1), B(1)], [A(2), B(2)], [A(3), B(3)], 'b');
plot3([B(1), C(1)], [B(2), C(2)], [B(3), C(3)], 'b');
plot3([C(1), A(1)], [C(2), A(2)], [C(3), A(3)], 'b');

fill3([A(1), B(1), C(1)], [A(2), B(2), C(2)], [A(3), B(3), C(3)], 'r');

xlabel('X');
ylabel('Y');
zlabel('Z');
