Hi,

I think you can try using Simulink thermistor block to build a circuit to convert analog input voltage to temperature. Other approach could be calculating resistance of thermistor using analog input voltage and a potential divider circuit. If the nominal resistance at a reference temperature (Ro) and characteristic temperature constant (B) are known, temperature can be calculated using log function in MATLAB.

1/T = log(R/Ro) + 1/To , where To is the reference temperature.

For more information on Simulink thermistor block, refer : https://www.mathworks.com/help/physmod/sps/ref/thermistor.html

Hope this helps.
