Function or variable 'ms1' not recognized

matlab2022b生成嵌入式代码报错

Function or variable 'ms1' not recognized

本人是手动点击生成代码（Ctrl+B）,并没有想过的脚步，

I manually clicked to generate the code (Ctrl+B) and did not take any steps forward,

Simulink会有时候弹出这个问题，我认为是simulink 自身的问题

Simulink sometimes pops up this issue, and I think it's a problem with Simulink itself

大家有没有遇到过类似的

Have you ever encountered something similar

Hi @Xiaoning.Wang

The error "Function or variable 'ms1' not recognized" usually means that Simulink or MATLAB cannot find a definition for 'ms1' in the current context. This is likely not a bug in Simulink itself, but rather due to one of the following -

1. Missing Workspace Variable: If 'ms1' is supposed to be a variable, make sure it is defined in the MATLAB base workspace before generating code (Ctrl+B). This can be checked by typing 'whos' in the Command Window.

2. Unresolved Block/Function Name: If 'ms1' refers to a block or model component, make sure it exists in your model and is correctly referenced. Sometimes renaming or deleting blocks can leave stale references.

3. Model Callbacks or Scripts: Check if your model relies on any 'InitFcn' callbacks or 'LoadFcn' scripts to initialize variables like 'ms1'. If those scripts are not executed, the variable might not exist.

I hope this helps
