Hi, a section of my code is as follows:

insertmy formula for entropy is : entropyxy = SUM(from i=1 to N) log(2*result(i))Code:for (i = 0; i < N; i++){ result[0] = distance(myPoints[i], myPoints[(i+1)%N]); printf("first distance:%f\n", result[0]); for (j = 0; j < N; j++){ if (i == j) continue; dis[i] = distance(myPoints[i], myPoints[j]); printf("%d %d\n", i, j); printf("%f\n", dis[i]); if (result[0] > dis[i]) result[0] = dis[i]; } if(result[0] != 0) {entropyxy[i] += (log(2*result[0])); } printf("shortest: %f\n", result[0]); }

However, my entropyxy doesn't seem to increment as it stands in my code. It only computes log(2*result[0]) but doesn't add this onto the previous value of the entropyxy i.e. entropyxy[i-1]. any help on how to solve this?

N.B result[0] changes for each value of i. (it is the shortest distance to a point)

thanks
