could you please tell me how to avoid Nan while code is getting executed.

I can if you share your code. You may use isnan.

@Prabha: To avoid the creation of NaN value, you have to avoid to perform calculations, which have NaN as result. There is no general way to "avoid" them, because they are the mathematically correct result for certain operations.

You get e.g. NaN for the numerical value of an imported Excel file, if the corresponding cell contains a string. Or you get NaN, if you divide by 0. If you need a method to catch this, post the relevant part of your code, as usual.
