function convertColumnToString(matrix, col) {
    const rows = matrix.length;
    let result = '';

    for (let i = 0; i < rows; i++) {
        result += matrix[i][col].toString();
        result += ' ';
    }

    return result.trim();
}

const matrix = [
  [ 4,  7,  9, 18, 29, 0],
  [ 1,  9, 18, 99,  4, 3],
  [ 9, 17, 89,  2,  7, 5],
  [19, 49,  6,  1,  9, 8],
  [29,  4,  7,  9, 18, 6]
];

const col = 3;

const str = convertColumnToString(matrix, col);

console.log(str);

 
 
 
/*
run:
 
18 99 2 1 9
 
*/
