JAVA sorting numbers, writing the highest one from each line in matrix


Try this. Please excuse the errors, but I typed it straight here, no testing. You can get the gist of the solution though.

class Results {
   int order, result;
   //getters and setters

   public int compareTo(Object o) {
      if (o instanceof Results) {
          Results r=(Results) o;
          return(new
Integer(result)).compareTo(r.getResult());
      }
      return(0);
   }
}

public int maxNumberInLine (int i) {   
            int max = b[i][0];
            for(int j=1; j<b[i].length; j++)
                if(max < b[i][j]) {
                    max = b[i][j] ;
                }
            return(i);        
    }

public void getPodium() {
    List<Results> results=new
ArrayList<Results>();
    for (int i=0; i<b.length; i++) {
        Results r=new Results();
        r.setOrder(i);
        r.setResults(maxNumberInLine(i));
        results.add(r);
    }
    Collections.sort(results);
    //Now the podium is composed of the first
three positions of the arraylist.
}

sorting matrix in matlab based on another vector
How about: ModifiedA=A(RowVector,ColumnVector); Note: Matab's indexing starts at 1 not at 0, adapt your indexing vectors accordingly.

Writing a parser for a matrix-like input with Boost Spirit
You need to break down your expressions to something like this: rows: DOUBLE | rows ',' DOUBLE columns: rows | rows ';' rows matrix: IDENTIFIER '.' '{' IDENTIFIER '}' '=' '[' columns ']' Now you can have a vector<double> for your rows. A vector< vector<double> > for your columns, and save the result in your matrix. Of course, when you get a columns in your matrix, you shoul

Eigen sparse matrix multiplications seem to compute full matrix
Basically, the document is sightly confusing for me at least. the way to do it is simply: SpMat mat_3 = mat_1 * mat_2 No dense matrix is created along the way. Eigen rocks!

You can convert all nan values to zeros using np.nan_to_num() and then proceed further. Demo: >>> data array([[ 5.1, 3.5, 1.4, 0.2], [ 4.9, 3. , nan, 0.2], [ 4.7, 3.2, 1.3, nan], [ nan, 3.1, 1.5, 0.2]]) >>> np.cov(data.T) array([[ nan, nan, nan, nan], [ nan, 0.04666667, nan, nan],

matrix inside matrix when multiplying symbolic matrices
The problem seems to be the K = C2^(16/57). Taking the root of a matrix is not trivial and solutions don't always exist. That's why MATLAB cannot resolve this expression. Try for example: A = syms('A',[3,3]); % create 3x3 symbolic matrix B = A^(1/3); % calculate the 3rd root of A The result will be ans = matrix([[a1_1, a1_2, a1_3], [a2_1, a2_2, a2_3], [a3_1, a3_2, a3_3]])^(1/3)
