There are many initial creation methods for mat. The following lists some of my favorite methods and some precautions during use. A basic knowledge of using mat is that it can be divided into two parts: "Data header + Data body", and the two parts can be separated in the memory, the production process does not require the concurrency/order to complete the whole process. Therefore, the existence mode of a mat variable includes: Short, header + body. In addition, the data body can be shared with o
