tuple_logtuple_logTupleLogTupleLogtuple_log (算子)
名称
tuple_logtuple_logTupleLogTupleLogtuple_log — 计算元组的自然对数。
签名
Herror tuple_log(double T, double* Log)
Herror T_tuple_log(const Htuple T, Htuple* Log)
def tuple_log(t: MaybeSequence[Union[float, int]]) -> Sequence[float]
def tuple_log_s(t: MaybeSequence[Union[float, int]]) -> float
描述
tuple_logtuple_logTupleLogTupleLogTupleLogtuple_log computes the natural logarithm of the input tuple
TTTTtt. The natural logarithm is always returned as a floating
point number. The natural logarithm of a string is not allowed.
例外：空输入元组
If the input tuple is empty, the operator returns an empty tuple.
HDevelop 内联操作
HDevelop provides an in-line operation for tuple_logtuple_logTupleLogTupleLogTupleLogtuple_log,
which can be used in an expression in the following syntax:
Log := log(T)
执行信息
- 多线程类型：独立（即使使用独占算子也能并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。
