WebIn a land acquisition, random noise can be created by the acquisition truck, vehicles, and people working in the survey area, wind, electrical power lines, and animal movement. This noise appears in a seismic record as spikes. In a marine acquisition, random noise can be created by ship props, drilling, other seismic boats, and wind/tidal waves. WebDec 28, 2024 · To restate and simplify: the standard uniform distribution selects numbers between 0 and 1. The numbers between 0 and 1 have a uniform probability of being selected. Outside of 0 and 1, the probability of selecting a number is 0. So that’s essentially what np.random.rand does. WebThe randn function generates pseudo-random numbers whose elements are normally distributed with mean 0 and variance 1 (standard normal). Both functions have the same syntax. For example, rand(n) returns a n-by-n matrix of random numbers, rand(n,m) returns a n-by-m matrix with randomly generated entries distributed uniformly between 0 and 1 ... my twin meme
