I am using a Simulink Model originally developped under Matlab R2018a. The model is composed mostly of matlab functions blocks are more basic blocks. There is no other specific module needed than the ones included in Simulink.
The model runs fine in my R2018b matlab version.
But i have to make it run in Matlab R2015a version, because it's the only matlab version installed on the cluster i work on.
So I just Exported the model to previous version as it is suggested by matlab.
I got erros like "Undefined function or variable <my_variable>. The first assignment to a local variable determines its class"
This error occurs for only 2 variables in the whole model. These two act both as input and output for some functions. I attached a screenshot of the errors displayed by Simulink.
I am struggling with this issue because my model works perfectly on my local machine (where i have R2018b installed).
Do you think this might be only a version problem or a deeper error may have occured ?
Thank you for any help or tips on this issue
I wish you a very good day.
