Matlab:加载.mat文件，为什么是结构?我可以将存储的vars加载到内存中吗? [英] Matlab: loading a .mat file, why is it a struct? can I just have the stored vars loaded into memory?

问题描述

相关代码:

function result = loadStructFromFile(fileName, environmentName) 
    result = load(fileName, environmentName);


bigMatrix = loadStructFromFile('values.mat','bigMatrix'); 

但是当我在工作区中查看时，它显示'bigMatrix'为1x1结构.但是，当我单击该结构时，它就是实际数据(在本例中为998x294矩阵).

But when I look in the workspace, it shows 'bigMatrix' as a 1x1 struct. When I click on the struct, however, it is the actual data (in this case a a 998x294 matrix).

推荐答案

作为

As the documentation of LOAD indicates, if you call it with an output argument, the result is returned in a struct. If you do not call it with an output argument, the variables are created in the local workspace with the name as which they were saved.

对于函数loadStructFromFile，如果保存的变量名称可以具有不同的名称(我假设为environmentName)，则可以通过写操作返回变量

For your function loadStructFromFile, if the saved variable name can have different names (I assume environmentName), you can return the variable by writing

function result = loadStructFromFile(fileName, environmentName) 
    tmp = load(fileName, environmentName);
    result = tmp.(environmentName);
