这篇博客介绍了MATLAB可支持的文件格式，包括能通过Import Wizard和importdata函数导入的类型，如不支持netCDF、H5、Motion JPEG 2000和特定平台的视频格式。

File Formats - Supported file formats

Description

This table shows the file formats that you can import and export from the MATLAB application.

You can import any of these file formats using the Import Wizard or the importdata function, except:

netCDF
