如何将具有结构的matfile保存为仅具有数组的matfile

Question

我有一个名为C875.004-03.B401的matfile。包含结构C1的mat。C1是包含100个变量的1X1结构。我想删除结构并保存matfile，这样当我在matlab中加载它时，它只是100个变量的数组。任何想法吗?谢谢你的帮助!

Answer 1

或者只使用save和-struct选项-

load('C875.004-03.B401.mat')
save('C875.004-03.B401.mat','-struct','C1')

它在我的MATLAB版本的文档中-

-struct'
Keyword to request saving the fields of a scalar structure as individual variables in the file. The structName input must appear immediately after the -struct keyword.

它在Mathworks帮助中也有示例，如这里引用的-

Create a structure, s1, that contains three fields, a, b, and c.
s1.a = 12.7;
s1.b = {'abc',[4 5; 6 7]};
s1.c = 'Hello!';
Save the fields of structure s1 as individual variables in a file called newstruct.mat.
save('newstruct.mat','-struct','s1');
Check the contents of the file using the whos function.
disp('Contents of newstruct.mat:')
whos('-file','newstruct.mat')
Contents of newstruct.mat:
  Name      Size            Bytes  Class     Attributes
  a         1x1                 8  double              
  b         1x2               262  cell                
  c         1x6                12  char

您可以使用matfile类，它可以帮助加载和保存数据到垫子文件。下面是您的案例的示例。我假设所有变量都存储在名为str的单个结构字段中的数组中。如果不是这样，请纠正我。

matObj = matfile('/path/to/C875.004-03.B401.mat');
matObj.C1=matObj.C1.str;

现在，C1应该是一个数组
