MATLAB结构合并 [英] MATLAB structure merge

问题描述

我有以下结构

data = 

                       id: [143x1 double]
                  datenum: [143x1 double]
                Timestamp: {143x1 cell}
         Min_F1_USA_40__u: [143x1 double]
         Max_F1_USA_40__u: [143x1 double]
        Mean_F1_USA_40__u: [143x1 double]
      Stddev_F1_USA_40__u: [143x1 double]
    MeanVals_F1_USA_40__u: [143x1 double]
          a0_F1_USA_40__u: [143x1 double]
          a1_F1_USA_40__u: [143x1 double]
          a2_F1_USA_40__u: [143x1 double]
          a3_F1_USA_40__u: [143x1 double]
      a4_F1_USA_40__u: [143x1 double]

如此，我在结构中有50多个字段

So on, I have more than 50 field in the struct

我还有其他3个结构相同的结构，我想合并此结构

I have other 3 structure with the same structure and I want to merge this struct

当我有3个结构体时，我将得到以下结构体

When I have 3 struct I will get the following structure

data = 

                       id: [429x1 double]
                  datenum: [429x1 double]
                Timestamp: {429x1 cell}
         Min_F1_USA_40__u: [429x1 double]
         Max_F1_USA_40__u: [429x1 double]
        Mean_F1_USA_40__u: [429x1 double]
      Stddev_F1_USA_40__u: [429x1 double]
        .
        .
        .

推荐答案

对不起，我误解了您的问题-这是第二次尝试.

Sorry, I had misunderstood your question - here a second try.

也许有一种更简单的方法，但是您可以使用mynames=fieldnames(data)获取data中所有字段的列表.然后，您可以遍历它们，并将它们分配给一个通用结构，如下所示:

Maybe there is an easier way, but you can get a list of all fields in data using mynames=fieldnames(data). You can then loop through them all and assign them to a common struct like this:

combineddata.(mynames{i})=[data1.(mynames{i}); data2.(mynames{i}); data3.(mynames{i})];
