Need help developing code using Matlab functions to determine the thermal resistance Requiv of a building?

• First function must read in the building measurements (length,width,height), and return values to base workspace. Use input validation to ensure all 3 values are >0.
• Second function uses these 3 measurements to calculate the floor, roof and wall surface area, as well as the mass of the air in the building. Values then returned to workspace.
• Third function uses 3 area values to determine thermal resistance. It asks the user for U-values for each floor, wall-door, and roof material and returns Requiv to base workspace.
• Fourth function summarises the results (building measurements, Requiv , mass of air)
