Hi 艳荣,

As I can understand from the translation in English, I see that you are facing issues with generating C Code. The error that you are facing in here is quite common and can be easily resolved.
The error part saying, “The block diagram 'Ramjet' is not loaded” tells that the model you are trying to generate code for is not correctly loaded. You can load the model by using the command:
load_system <model name>
Once it loaded, it is always beneficial to check if it has been loaded correctly. You can do this by using the command:
which <Model name> -all
In a rare case that this does not solve your error, check for duplicates of the "coderInfo.mat" file and remove the ones unrelated to the project.
