org.ejml.simple.SimpleMatrix.elementSum()

Examples of org.ejml.simple.SimpleMatrix.elementSum()

    for (int i = 0; i < output.numRows(); ++i) {
      for (int j = 0; j < output.numCols(); ++j) {
        output.set(i, j, Math.exp(output.get(i, j)));
      }
    }
    double sum = output.elementSum();
    // will be safe, since exp should never return 0
    return output.scale(1.0 / sum);
