monthly temperature data
I'm probably having quite a simple problem. I am creating a model similar to the 'degree days' model in the library. However instead of having T_m as a graphed input, I would like it to come in as data from a file. I have tried creating a .csv file with two columns, month and temperature and loading it in through the table command on the equation dialogue box. However I do not know what to write in the Equation box. At the moment it says table(). if I add 'temperature' or 'month' in the brackets it complains that these parameters do not exist in the model.
I've tried quite a few other things like fixed parameters, or creating an array, but then this stops the flow equation from working.
What is the easiest way to include the monthly data from a file?
For working with the table
For working with the table function see the table help.
The preferred solution would be to use variable paramters to to handle a time series see, http://www.simulistics.com/help/data/time.htm. Variable parameters are needed instead of fixed so that the parameter can change over time.
