时间步长之间的​​计算装置，用于在MATLAB给定持续时间的值 [英] Compute means between time steps for given duration values in MATLAB

问题描述

例如，我有5个步骤，时间和持续时间值：

For example, I have 5 time steps and a duration value:

TimeSteps = [4, 5, 6, 7, 8, 10, 11, 12, 14, 15, 16];
Duration = [5, 3, 3];

我想自动生成对于每个持续时间的时间步长之间的​​装置。在这种情况下，结果是这样的：

I want to automatically generate the means between the time steps for every duration. In this case, the result would look like this:

Result = [mean([4, 5, 6, 7, 8]), mean([10, 11, 12]), mean([14, 15, 16])]; 

这会导致：

Result = [6, 11, 15]; 

我有一个474x1时间矢量，所以我需要你完成这项。如果有人可以帮助，这将是巨大的。谢谢。

I have a 474x1 duration vector, so I need to automatize this. If anyone can help, it would be great. Thank you.

推荐答案

您需要将的意思是功能应用到你的时间步<的一个分区/ code>是在持续时间尺寸：

You need to apply the mean function to a partition of your TimeSteps that has the sizes in Duration:

Partition = mat2cell(TimeSteps, 1, Duration);
Result    = cellfun(@mean, Partition)

如果你是单行的粉丝：

Result = cellfun(@mean, mat2cell(TimeSteps, 1, Duration));

的注：的请您考虑这个解决方案是张贴行向量;修改 mat2cell 要求的列向量。

Note: Please take in account that this solution is posted for row vectors; change the mat2cell call for column vectors.
