I am having an array of length 1669965*1 double. There are some NAN's in it which are intermixed with the required data.
I am trying the convert NAN's to 0 without changing the length of the array.
Charge_P = Charge_P(isnan(Charge_P))=0;
I am getting an error saying i have to use '==' but if i use it it is modifying the length of my array.

You can't have two assignment operators (the equals sign) in a single command. I think you just want this
Charge_P(isnan(Charge_P))=0;
You might also be insterested in the fillmissing function.
Charge_P = fillmissing(Charge_P,'constant',0)
