may help you . There is really no reason to use raw pointers in your scenario. I'd suggest holding the board as a single dimensional std::vector, and simply use multiplication to of the row/column when iterating the board.

will be helpful for those in need Matlab, as you know, indexes from 1 so you will need to add 1 to the index 0,1,2 to get the row identifier for h. So if the input is 'index'
code :
j = h(index+1,:)
j = [j h(index+1,:)]

fixed the issue. Will look into that further JSON can do the trick, but why not look at it from another angle?
If you're pinging PHP to get updated info, just have PHP output the option values you want in your select box. Then use the HTML return of jQuery AJAX to .html() the result into your select element.

it helps some times Same as How to create a generic array in Java? but extended to 2D:
code :
import java.lang.reflect.Array;

public class Example <T> {

    private final Class<? extends T> cls;

    public Example (Class<? extends T> cls) {
        this.cls = cls;
    }

    public void arrayExample () {
        // a [10][20] array
        @SuppressWarnings("unchecked")
        T[][] array = (T[][])Array.newInstance(cls, 10, 20);
        System.out.println(array.length + " " + array[0].length + " " + array.getClass());
    }

    public static final void main (String[] args) {
        new Example<Integer>(Integer.class).arrayExample();
    }

}
T[] array = (T[])Array.newInstance(cls, d1);
T[][] array = (T[][])Array.newInstance(cls, d1, d2);
T[][][] array = (T[][][])Array.newInstance(cls, d1, d2, d3);
T[][][][] array = (T[][][][])Array.newInstance(cls, d1, d2, d3, d4);
T[][][][][] array = (T[][][][][])Array.newInstance(cls, d1, d2, d3, d4, d5);

help you fix your problem If I understood your question correctly, you can obtain almost what you want using this (tested with CakePHP 3):
code :
Hash::combine($array, '{n}.user', '{n}', '{n}.age') ;
array_map('array_values', Hash::combine($array, '{n}.name', '{n}', '{n}.age'))
array_map('array_values', Set::combine($array, '{n}.name', '{n}', '{n}.age'))
$array = array(
    0 => array(
        'name' => "Bob",
        'age'  => 20,
        'marks'=> 50
    ),
    1 => array(
        'name' => "Ryan",
        'age'  => 20,
        'marks'=> 57
    ),
    2 => array(
        'name' => "Allen",
        'age'  => 23,
        'marks'=> 70
    ),
    3 => array(
        'name' => "Duke",
        'age'  => 23,
        'marks'=> 67
    ),
    4 => array(
        'name' => "Matt",
        'age'  => 24,
        'marks'=> 85
    )
) ;
debug($array);
debug(\Cake\Utility\Hash::combine($array, '{n}.user', '{n}', '{n}.age'));
debug(array_map('array_values', \Cake\Utility\Hash::combine($array, '{n}.name', '{n}', '{n}.age')));

wish of those help I can't get around the below problem and any help would be greatly appreciated , Perhaps something like this?
code :
Sub tgr()

    Dim aTemp As Variant
    Dim aData As Variant
    Dim iyTemp As Long
    Dim iyData As Long
    Dim ix As Long

    With ActiveWorkbook.Sheets("PF File Simple").Range("A2").CurrentRegion
        aTemp = .Value
        ReDim aData(1 To WorksheetFunction.CountIf(.Resize(, 1).Offset(, 1), 0), 1 To .Columns.Count)
    End With

    For iyTemp = 1 To UBound(aTemp, 1)
        If aTemp(iyTemp, 2) = 0 Then
            iyData = iyData + 1
            For ix = 1 To UBound(aTemp, 2)
                aData(iyData, ix) = aTemp(iyTemp, ix)
            Next ix
        End If
    Next iyTemp

    'aData is now populated with only values where the second column is 0

End Sub
