Matlab如何对时间范围进行分组 [英] Matlab how to group time ranges

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
