1、linspace(x, y)
产生一个有100个元素的行向量,其中的元素在区间[x, y]中等间隔分布。
如 linspace(1,10)
1.0000 1.0909 1.1818 1.2727 1.3636 1.4545 1.5455 1.6364 1.7273
1.8182 1.9091 2.0000 2.0909 2.1818 2.2727 2.3636 2.4545 2.5455
2.6364 2.7273 2.8182 2.9091 3.0000 3.0909 3.1818 3.2727 3.3636
3.4545 3.5455 3.6364 3.7273 3.8182 3.9091 4.0000 4.0909 4.1818
4.2727 4.3636 4.4545 4.5455 4.6364 4.7273 4.8182 4.9091 5.0000
5.0909 5.1818 5.2727 5.3636 5.4545 5.5455 5.6364 5.7273 5.8182
5.9091 6.0000 6.0909 6.1818 6.2727 6.3636 6.4545 6.5455 6.6364
6.7273 6.8182 6.9091 7.0000 7.0909 7.1818 7.2727 7.3636 7.4545
7.5455 7.6364 7.7273 7.8182 7.9091 8.0000 8.0909 8.1818 8.2727
8.3636 8.4545 8.5455 8.6364 8.7273 8.8182 8.9091 9.0000 9.0909
9.1818 9.2727 9.3636 9.4545 9.5455 9.6364 9.7273 9.8182 9.9091
10.0000
2、linspace(x, y, n)
x起始值,y终止值,n向量个数
如linspace(2, 6, 3)得到
ans =
2 4 6
