Simulink block for transforming 2D matrix to two 1D marices

Hi,

Does anyone have an idea which block should I use to separate the two columns of one 2D matrix. Now the matrix is: Input: [10 | 20] [21 | 15] [14 | 10] [13 | 86]

but I want the columns to be separated in two separated 1D matrices: Output: First matrix [10] [21] [14] [13] Second matrix [20] [15] [10] [86]

Thank you very much.
