I have a variable X=csvread('XXXX'); with huge data in it.

My function is written in a .m fileĀ  "MyPrg.m" and it uses the data in X and have reference to that variable.

Whenever I call MyPrg in command line it give me error 'X' is undefined , however I dont have "clear" in my function
It should recognize the global variable X.

I can not afford to read that huge file everytime in my function code.

Please help

Thanks and Regards
