Matlab如何对时间范围进行分组

本文介绍了Matlab如何对时间范围进行分组的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有以下几次

1.1 1.15 1.19 1.32 1.69 2.12 2.36 2.86 3.25 3.67 3.77 3.91 ...

我希望MALTAB读取时间并将数字存储到数组中，其中数组1将在1-2秒内出现一次.阵列2将为2-3秒，依此类推.

And I would like MALTAB to read the times and store the numbers into arrays where array 1 would be for times in 1-2 seconds. Array 2 would be 2-3 seconds and so on.

在此先感谢您提供的帮助/建议

Thanks in advance for any help/advice given

推荐答案

您可以使用 accumarray 将这些数组存储为单元格数组的单元格，就像这样-

You could use accumarray to have those arrays stored as cells of a cell array, like so -

groups = accumarray(floor(timeseries),timeseries,[],@(x){x})

样品运行-

>> timeseries timeseries = 1.1 1.15 1.19 1.32 1.69 2.12 2.36 2.86 3.25 3.67 3.77 3.91 >> groups = accumarray(floor(timeseries),timeseries,[],@(x){x}); >> celldisp(groups) %// Display cells of output groups{1} = 1.1 1.15 1.19 1.32 1.69 groups{2} = 2.12 2.36 2.86 groups{3} = 3.25 3.67 3.77 3.91
