Question

我想将LUA表保存为MAT文件。表的结构如下：

{
  1 : 
    {
      bounding_box : 
        {
          1 : 0.5
          2 : 0.5
          3 : 704.5
          4 : 1280.5
        }
      PatchName : "03952.jpg"
      confidence : 
        {
          1 : 0.99999818651222
          2 : 1.8134877758073e-06
        }
    }
  2 : 
    {
      bounding_box : 
        {
          1 : 45.5
          2 : 159.5
          3 : 132.5
          4 : 216.5
        }
      PatchName : "03953.jpg"
      confidence : 
        {
          1 : 0.99999864618192
          2 : 1.3538180818906e-06
        }
    }
 }

有人能指导我怎么做吗？

我尝试了matio.save（路径字符串，要保存的表）但是它返回了以下错误：

bad argument #1 to 'varCreate' (cannot convert 'number' to 'const char *')
stack traceback:
    [C]: in function 'varCreate'

安装并使用https://github.com/soumith/matio-ffi.torch，例如：

if(progressDialog!=null) progressDialog.dismiss(); // to prevent memory leak

如何将LUA表转换为matlab MAT文件？
