How do I transfer real time changing variables from MATLAB to Simulink?

Hi everybody, I'm struggling against a real big problem to me. I have a MATLAB script which gets data from an UART sensor. Now I have to create a scheme in Simulink and, to do so, I need to give to Simulink the real time data acquired via MATLAB. I really don't know how to do it. I have tried many ways without any success. Do you know if there ara any way to do so?

hi,

can you elaborate... you can directly use simulink blocks from Instrument Control Toolbox to read data from sensor

Yeah, I have tried...I'm using a sensor connected to Raspberry and using the Raspberry Serial block I get ascii chars in decimal. And, using a Linux system, I wasn't be able to decode the Ascii code from the sensor. So I had to do in this way
