ndarray-多元高斯 从多元高斯分布中抽取样本 例子 import ndarray from 'ndarray' ; import mvGaussian from 'ndarray-multivariate-gaussian' ; const mean = ndarray ( [ 1 , 2 ] ) ; const covariance = ndarray ( [ 4 , 1 , 1 , 2 ] , [ 2 , 2 ] ) ; const N = 10 ; // Draw N samples from a 2-dimensional Gaussian distribution let samples = mvGaussian ( mean , covariance , N ) ; console . log ( samples . shape ) ; // [2, 10] // Dr
