Numpy is the library of function that helps to construct or manipulate matrices and vectors. The function numpy.tanh(x) is a function used for generating a matrix / vector / variable with the Tangent Hyperbolic value of b x (as tanh(x)).
Numpy是一个功能库,可帮助构造或操纵矩阵和向量。 函数numpy.tanh(x)是用于生成正切双曲值为b x的矩阵/向量/变量(作为tanh(x) )的函数 。
