How to use the ml-matrix.NIPALS function in ml-matrix

_computeWithNIPALS(dataset, nCompNIPALS) {
    this.U = new Matrix(nCompNIPALS, dataset.columns);
    this.S = [];

    let x = dataset;
    for (let i = 0; i < nCompNIPALS; i++) {
      let dc = new NIPALS(x);

      this.U.setRow(i, dc.w.transpose());
      this.S.push(Math.pow(dc.s.get(0, 0), 2));

      x = dc.xResidual;
    }
    this.U = this.U.transpose(); // to be compatible with API
  }
}
