Hello Ali,

I reproduced the same error on my end with MATLAB R2023b and figured it’s about a variable name not being resolved in the model. The variable “YY” is not loaded into the workspace, nor is it instantiated in the MATLAB script that you have provided i.e. “LDA_1801k8_IMP.m”. Hence, it would not be used as an external input to the model. A workaround for this is to either instantiate a variable named “YY” or change the variable name in “Configurations Parameters”.

Additionally, the expression “YY.getElement(1)” is not a valid MATLAB expression as the function “getElement” is used to access data/interface using the element name. Please refer to the below documentation to know more about the different use cases of “getElement” function and how to use it:

Hope it helps!
