Hi Community,

i am currently working on a project where a wrote a matlab function to read sensor data. The function is running and displaying the data in the command window. I now want to use that data in simulink so i want to save the data to the base workspace to access it via simulink.

I have tried the global variable and the assignin command so far, but the variables update just after the script is finished but i want it to update while the script is running. Does anyone know a solution for this issue.

Thanks a lot

P.S. Matlab function block can not be used in simulink since some functions are not supported for code generation, which is critical

Use the MATLAB Function block.

Thanks for your response, I already implemented this solution but for some critical functiions called inside the function, the block does not support code generation, what is critical

Did you use coder.extrinsic()?
