Question

可以使用

将

.mat个文件加载到Python中

import scipy.io
matdata1 = scipy.io.loadmat('file1.mat')
matdata2 = scipy.io.loadmat('file2.mat')

然后可以通过管道传输文件，并通过调用以下Python函数将mat文件保存为文本：

def mat2txt(matdata):
    for k, v in matdata.items():  #Python 3 specific
        if isinstance(v,dict):
            myprint(v)
        else:
            print (k,v)

正在比较的两个.mat文件具有相同的结构和类型，具有不同的值。

我希望能够以人类可读的格式识别不同的值，而不仅仅是它们的位置。

我试过了：

diff matdata1.txt matdata2.txt 
diff matdata1.txt matdata2.txt | grep "<" | sed 's/^<//g' 
grep -v -F -x -f matdata1.txt matdata2.txt

没有指出值的具体差异，并且它们不在Python中。我希望将.mat文件存储为.txt，以便能够创建静态状态，以比较不同日期的文件数据相对于自身和其他文件，以及提供存储的机会。 git用于将来的比较。

结果数据文件的玩具示例是：

matdata1.txt

如何在人类可读的格式中找到Python中mat文件的差异？
