如何自动分析存储在mat文件中的矩阵?

时间：2021-07-04 18:15:24

I've got a multidimensional .mat file with a bunch of m x n arrays where each one is called something different, for example f1, f2, etc. I want to open the .mat file up and analyze each file automatically. How do I do that?

我有一个多维的。mat文件，其中有很多mxn数组，每个数组都有不同的名称，例如f1、f2等等。我想打开。mat文件并自动分析每个文件。我该怎么做呢?

If you know for certain that all the variables in the .mat file are M-by-N arrays to be processed, then this should work:

如果您确定.mat文件中的所有变量都是要处理的m×n数组，那么这应该是可行的:

data = load('your_file.mat');   %# Load .mat file data into a structure
for name = fieldnames(data).'  %'# Loop over the field names of the structure
  mat = data.(name{1});         %# Get one structure field (i.e. matrix)
  %# Process matrix here
end

The above uses the functions load and fieldnames, and accesses structure fields using dynamic field names.

上面使用函数load和fieldname，并使用动态字段名访问结构字段。
