Logarithm

Detailed Description

These functions allows performing logarithm computations

Variables
constexpr auto	eve::log = functor<log_t>
	elementwise_callable object computing the natural logarithm: \(\log x\).
constexpr auto	eve::log10 = functor<log10_t>
	elementwise_callable object computing the base 10 logarithm: \(\log_{10} x\).
constexpr auto	eve::log1p = functor<log1p_t>
	elementwise_callable object computing the natural logarithm of \(1+x\): \(\log(1+x)\).
constexpr auto	eve::log2 = functor<log2_t>
	elementwise_callable object computing the base 2 logarithm: \(\log_2 x\).
constexpr auto	eve::log_abs = functor<log_abs_t>
	Callable object computing the natural logarithm of the absolute value of the input.
constexpr auto	eve::logspace_add = functor<logspace_add_t>
	tuple_callable object computing the logspace_add operation: \(\log\left(\sum_{i = 0}^n e^{\log x_i}\right)\)
constexpr auto	eve::logspace_sub = functor<logspace_sub_t>
	tuple_callable object computing the logspace_sub operation: \(\log\left(e^{\log x_0}-\sum_{i = 1}^n e^{\log x_i}\right)\).
