Web29. máj 2013 · Your sphereFN may not be doing what you expect it to do. It looks like you are trying to implement a sum of different powers test based on this function: However, your implementation as: ph = sum (x.*x, 2); does not resemble that function. How about using this as a starting point: Web24. mar 2024 · A sphere is defined as the set of all points in three-dimensional Euclidean space that are located at a distance (the "radius") from a given point (the "center").

Web15. feb 2013 · The Fermi GPUs have Special Function Units (SFUs) to (quoting the NVIDIA White Paper on Fermi) "execute transcendental instructions such as sin, cosine, reciprocal, and square root. Each SFU executes one instruction per thread, per clock". My questions are: Do SFUs operate on single and double precision numbers or on single precision only? WebThe sphere function is one of many test functions that are being used in the literature. In applied mathematics, these test functions, or artificial landscapes, are useful to assess the performance of an algorithm, or a proposed modification of an algorithm.
