talib.LN

The talib.LN() function is used to calculate the Vector Log Natural (natural logarithm).

The return value of the talib.LN() function is a one-dimensional array. array

talib.LN(inReal)

The inReal parameter is used to specify the K-line data. inReal true {@struct/Record Record} structure arrays, numeric arrays

function main() {
    var data = [1, 2, 3]
    var ret = talib.LN(data)
    Log(ret)
}

import talib
import numpy as np
def main():
    data = [1.0, 2.0, 3.0]
    ret = talib.LN(np.array(data))
    Log(ret)

void main() {
    std::vector<double> data = {1, 2, 3};
    auto ret = talib.LN(data);
    Log(ret);
}

The LN() function is described in the talib library documentation as: LN(Records[Close]) = Array(outReal)
