acoth method

Matrix acoth()

Element-wise hyperbolic arc-cotangent

Implementation

Matrix acoth() {
  Matrix result = Matrix.zeros(rowCount, columnCount, isDouble: true);
  for (int i = 0; i < rowCount; i++) {
    for (int j = 0; j < columnCount; j++) {
      num val = this[i][j];
      result[i][j] = 0.5 * math.log((val + 1) / (val - 1));
    }
  }
  return result;
}
