Matlab可以把生成的数据导入excel,VC调用Matlab引擎却不可以,为什么

程序如下：
void CMyDlg::OnHuiDuGongSheng()
{
// TODO: Add your command handler code here

engEvalString(ep,"Gray=imread('121.bmp');");
engEvalString(ep,"[M,N,O] = size(Gray);");
engEvalString(ep,"M = 128;");
engEvalString(ep,"N = 128;");

//为了减少计算量，对原始图像灰度级压缩，将Gray量化成16级
engEvalString(ep,"for i = 1:M;\
for j = 1:N;\
for n = 1:256/16;\
if (n-1)*16<=Gray(i,j)&&Gray(i,j)<=(n-1)*16+15;\
Gray(i,j) = n-1;\
end;\
end;\
end;\
end;");

//计算四个共生矩阵P,取距离为1，角度分别为0,45,90,135
engEvalString(ep,"P = zeros(16,16,4);");
engEvalString(ep,"for m = 1:16;\
for n = 1:16;\
for i = 1:M;\
for j = 1:N;\
if j<N&&Gray(i,j)==m-1&&Gray(i,j+1)==n-1;\
P(m,n,1) = P(m,n,1)+1;\
P(n,m,1) = P(m,n,1);\
end;\
if i>1&&j<N&&Gray(i,j)==m-1&&Gray(i-1,j+1)==n-1;\
P(m,n,2) = P(m,n,2)+1;\
P(n,m,2) = P(m,n,2);\
end;\
if i<M&&Gray(i,j)==m-1&&Gray(i+1,j)==n-1;\
P(m,n,3) = P(m,n,3)+1;\
P(n,m,3) = P(m,n,3);\
end;\
if i<M&&j<N&&Gray(i,j)==m-1&&Gray(i+1,j+1)==n-1;\
P(m,n,4) = P(m,n,4)+1;\
P(n,m,4) = P(m,n,4);\
end;\
end;\
end;\
if m==n;\
P(m,n,:) = P(m,n,:)*2;\
end;\
end;\
end;");

//对共生矩阵归一化
engEvalString(ep,"for n = 1:4;\

//对共生矩阵计算能量、熵、惯性矩、相关4个纹理参数

engEvalString(ep,"Ux = H;");
engEvalString(ep,"Uy = H;");
engEvalString(ep,"deltaX= H;");
engEvalString(ep,"deltaY = H;");
engEvalString(ep,"C =H;");
engEvalString(ep,"for n = 1:4;\

H(n) = -P(i,j,n)*log(P(i,j,n))+H(n);\
end;\

end;\
end;");
