For real-valued input, log1p is accurate also for x so small that 1 + x == 1 in floating-point accuracy. Logarithm is a multivalued function: for each x there is an infinite number of z such that exp(z) = 1 + x. WebNumpy is the primary way to handle matrices and vectors in python. This is the way to model either a variable or a whole dataset so vector/matrix approach is very important when working with datasets. Even more, these objects also model the vectors/matrices as mathematical objects. chrome pdf 转图片
