柱体多边形建模：在Matlab中M文件显示正确，但在VC中无显示！

[astrider]

使用面片建立20个柱体，高度随机产生，M文件如下：
Z=rand(20)
figure
for i=1:4
for j=1:5
val=z[i*4+j];
vert=[i-0.5 j-0.5 0
i-0.5 j+0.5 0
i+0.5 j+0.5 0
i+0.5 j-0.5 0
i-0.5 j-0.5 val
i-0.5 j+0.5 val
i+0.5 j+0.5 val
i+0.5 j-0.5 val];
fac=[1 2 3 4;2 6 7 3;4 3 7 8;1 5 8 4;1 2 6 5;5 6 7 8];
h=patch(‘faces’,fac,’vertices’,vert,’FaceColor’,’r’);
end
end
grid on
view(3)

在Matlab中运行良好无误，我将这段代码加入到VC中，每一个语句前面加上

engEvalString，却不能显示，即：

engEvalString(m_ep,"Z=rand(20)");
engEvalString(m_ep,"figure");
engEvalString(m_ep,"for i=1:4");
engEvalString(m_ep,"for j=1:5");
engEvalString(m_ep,"val=z[i*4+j];");
engEvalString(m_ep,"vert=[i-0.5 j-0.5 0");
engEvalString(m_ep,"i-0.5 j+0.5 0");
engEvalString(m_ep,"i+0.5 j+0.5 0");
engEvalString(m_ep,"i+0.5 j-0.5 0");
engEvalString(m_ep,"i-0.5 j-0.5 val");
engEvalString(m_ep,"i-0.5 j+0.5 val");
engEvalString(m_ep,"i+0.5 j+0.5 val");
engEvalString(m_ep,"i+0.5 j-0.5 val];");
engEvalString(m_ep,"fac=[1 2 3 4;2 6 7 3;4 3 7 8;1 5 8 4;1 2 6 5;5 6

7 8];");
engEvalString(m_ep,"h=patch(‘faces’,fac,’vertices’,vert,’

FaceColor’,’r’);");
engEvalString(m_ep,"end");
engEvalString(m_ep,"end");
engEvalString(m_ep,"grid on");
engEvalString(m_ep,"view(3)");
其中的m_ep是我初始化的Matlab引擎。

哪位大侠知道为什么啊？？急救！

自问自答：在每一个语句后面加上分号就可以了。
