Hello can any one help me in specifying constraints for appliances like refregerator, lights, Clothesdryer, Dish_washer, Washing_Machine, oven, iron, Refrigerator, Lightening, Vaccume_cleaner, PoolPump, EWH (electric water heater), Hairdryer, AC and please also comments which appliance belong to which category, elastic, regular, interruptible, non interruptible, deferrable,non deferrable, interruptible and non deferrable?

Minute by minute comparisons would be data, not code.

Different models of the same appliances do not have the same cycle time, so if you want minute-by-minute information you need to go right into the brand and model.

"But the question is which functions etc would be used in MATLAB and how"

Mathworks does not provide any load data for appliances, so there are no applicable MATLAB functions.

You have not indicated what you want to do with the data once you have it, so it is difficult to advise you.

Residential loads can be divided into 3 subcatergory, these are non-deferrable, deferrable and thermostatically controlled (TC) ones. Non-deferrable loads can be modelled as statiscally (as pdf) because start time and operation duration depends on users' behavior, but it can be modelled as a constant load for a duration, example: a TV may consume 200 W power between 6-10 pm. Although it is unrealistic, it can be used for an algorithm to be tested. Deferrable loads' characteristics can be provided by a manufacturer as a catalog info. It may have power limits, energy constraints and so on. Third group includes AC, heater, refrigerator work based on heat dynamics of the ambient and occupation. It may not be so easy to model the heat dynamics for a specific ambient because it requires measurement. However, there are some papers in the literature providing generic model and regarding coefficients. Its switching pattern can be optimized accordingly.

To be able to do realistic work you should be able to log data from large scale community and extract related model parameters. Otherwise it will be hard to be implemented.
