对数间距数 [英] Logarithmically spacing number

问题描述

我想测试几个强度值.

I would like to test several values of intensity.

我需要将它们对数地从1到1000隔开.但是我只使用1、10、100、1000，但是我想有更多的数据点，比如说10.

I need them to be spaced logarithmically from 1 to 1000. Yet I just use 1, 10, 100, 1000, but I would like to have more data point, let`s say 10.

如何在Mathematica中找到10个对数间隔为1到1000的数字?

推荐答案

如果a开始，则c是结束，而b是间隔数:

If a is start, c is end and b is number of intervals:

{a, b, c} = {1, 10, 1000};
t = (c/a)^(1/b) // N
a*t^Range[b]

1.99526
{1.99526, 3.98107, 7.94328, 15.8489, 31.6228, 63.0957, 125.893, 251.189, 501.187, 1000.}

我使用N只是为了更好看，我们有什么.

I used N just to see better, what do we have.
