画上三角矩形三维图像

海纳百川

以对应的行数,列数和矩阵中的数据做出三维图像.我做了很久,怎么也做不出来,恳请高手指点.
E = [1.26E+09  1.26E+09  1.46E+09  1.56E+09  1.76E+09  2.06E+09  2.16E+09  2.36E+09  2.46E+09  2.56E+09  2.66E+09

THAT WOULD BE MORE CONVIENT IF YOU PUT THE MATRIX WITH THE FULL FORMAT.I BELIEVE THAT THE CODE SHOWN AS BELOW IS OR PARTLY IS WHAT YOU LOOKING FOR.

1. function TrilMatrixPlot
2. clc
3. E(1,:) = [1.26E+09  1.26E+09  1.46E+09  1.56E+09  1.76E+09  2.06E+09  2.16E+09  2.36E+09  2.46E+09  ...

10. E(7,:)=[2.88E+09  2.88E+09  2.98E+09  2.78E+09  3.08E+09  zeros(1,6)];
11. E(8,:)=[1.46E+09  1.56E+09  1.76E+09  2.06E+09   zeros(1,7)];

16. surf(x,y,E)
17. shading interp
18. hold on
19. plot3(x,y,E,'ro')
