In a program I need to use some values for only during the first execution of the function, thereafter the execution of the function will have to take the updated values. Is there anyway I can find the execution number from Matlab command?

Add this to the beginning of the code:
persistent number_of_executions
if isempty(number_of_executions); number_of_executions = 0; end
number_of_executions = number_of_executions + 1;
Now you can test if number_of_executions == 1

Well, your requirements are not clear. What I understood is, you have a script which calls different function files and you want to know which one executes 1st.
Considering this is your requirement, what I would suggest is, check the function file names from the folder of your script which will be in .m format and now in your script try to find the exact name amongst them. The functions are called in script by their file name hence 1st of them will be the 1st getting executed.
