There's no attachment but do you have the data as a matrix or a figure?

Looks like you simply want to extract the index of the max value from powerDensity vector,

 [maxPD,indx] = max(powerDensity);
 %now to find the distance, use this index on distance vector
 maxDist = distance(indx);

Thank you so much!
