How would write a code that for a vector that is 500 data points long, but the first 123 data points are NaN?

You first create the NaN vector using nan(), then fill in the elements.
V = nan (500,1);
V (124:end) = Data;

No. If you have your vector of values for 125 to 500 and you want to transfer them to the new vector, then you should use:
V = nan (500,1);
V (124:end) = Data;
Otherwise, if you have a 500 element vector and you want to eliminate the first 125 elements, then you can do it in one command (not the one you mentinoed):
Data (1:123) = NaN;
