Description

Re-order a matrix from Column order to Row order or from Row order to Column order.

bRowOrder: [input] If TRUE re-order to Row order and if FALSE re-order to Column order

Return

Returns TRUE on success or FALSE on failure.

Examples

EX1

// Reorder a matrix

{ 
    matrix<double> mat1 = {
        {1,  1,  1,  1},
        {2,  4,  6,  8},

    };
// Output of this sample code:
//   Reordered matrix in Row order is:
//      1    2    3     1
//      4    6    1     6
//      9    1    8    12
//   Reordered matrix in Column order is:
//      1    1    6     6
//      1    2    8     9
//      1    4    3    12
