MATLAB program for Resistance of the RTD

Write a MATLAB program which should include

  1. a prompt for entering the temperature
  2. finding out the resistance of the RTD (Resistance temperature detector) for the entered from the given data.
  3. performing linearization about the entered temperature point.
