I'm looking to calculate the following price weighted function using the average price data AvgPrice2019. It just results in NaN. Can someone help?
I still keep getting NaN. Do you know why?

Typing an answer would be easier, if you post the code as text, not as screenshot. Then the readers can copy&paste it to show a modification.

Start with using Matlab methods instead of the loops:
avg = AvgPrice2019;
meanAavg = sum(avg);
pweight = avg / meanAvg;
If this replies NaNs only, a value in avg is infinite:
avg(~isfinite(avg))
What do you see?
