1、blkdiag函数：生成指定对角线元素的矩阵

2、用法说明

A = blkdiag(a,b,c,d,...) 函数产生以a，b，c，d，...为对角线元素的矩阵A

3、举例说明

>> x = blkdiag(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16)

x =

1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

0 2 0 0 0 0 0 0 0 0 0 0 0 0 0 0

0 0 3 0 0 0 0 0 0 0 0 0 0 0 0 0

0 0 0 4 0 0 0 0 0 0 0 0 0 0 0 0

0 0 0 0 5 0 0 0 0 0 0 0 0 0 0 0

0 0 0 0 0 6 0 0 0 0 0 0 0 0 0 0

0 0 0 0 0 0 7 0 0 0 0 0 0 0 0 0

0 0 0 0 0 0 0 8 0 0 0 0 0 0 0 0

0 0 0 0 0 0 0 0 9 0 0 0 0 0 0 0
