ndarray-normalize:将 ndarray 归一化为零均值和单位方差

ndarray-归一化 对 ndarray 进行归一化，使均值为 0，标准差为 1。 例子 var moments = require ( "ndarray-moments" ) var lena = require ( "luminance" ) ( require ( "lena" ) ) console . log ( "Before normalization:" , moments ( 2 , lena ) ) require ( "ndarray-normalize" ) ( lena ) console . log ( "After normalization:" , moments ( 2 , lena ) ) 这打印出来： Before normalization: [ 124.04670674515125, 17677.59913617722 ] After n
