My current problem is that I need the full decomposition Q (m x m) instead of the thin one Q (m x n). Can somebody help me, what do I have to add to the algorithm to compute the full QR decomposition?. WebAs in the usual divide and conquer algorithms, it has three major steps: Divide: We divide the set of n points into two parts by a vertical line into the left and right halves. Conquer: We recursively find the convex hull on left and right halves. Combine or Merge: We combine the left and right convex hull into one convex hull. darlington building society account details

"Graham's scan is a method of finding the convex hull of a finite set of points in the plane with time complexity O(n log n). It is named after Ronald Graham, who published the original algorithm in 1972. The algorithm finds all vertices of the convex hull ordered along its boundary. It uses a stack to detect and remove concavities in the boundary efficiently. " - Graham algorithm python
