talib.COS

The talib.COS() function is used to calculate the Vector Trigonometric Cos (cosine function).

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

talib.COS(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 = [-3.14, 0, 3.14]
    var ret = talib.COS(data)
    Log(ret)
}

import talib
import numpy as np
def main():
    data = [-3.14, 0, 3.14]
    ret = talib.COS(np.array(data))
    Log(ret)

void main() {
    std::vector<double> data = {-3.14, 0, 3.14};
    auto ret = talib.COS(data);
    Log(ret);
}

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