Sort certain matrix cells in a vector

Hi there,

I would like to read out certain cells from a matrix (Start_Matrix) and write them in a vector (Goal_Matrix).

  Start_Matrix=[887.2659  222.9229   78.8083;
                895.9041  209.7397   83.3533;
                891.8674  216.4627   80.6671;
                964.2606  112.3682  112.3682;
                909.2908  188.5016   91.2047;
                881.3223  233.0634   74.6114;
                883.7692  231.4666   73.7613]

Goal_vector=[78.8083;83.3533;112.3682;188.5016;233.0634;231.4666]

How can I address the individual cells in the matrix directly?

What is the criteria to get Goal_vector?

That's my goal ;-).

How can I do this?

Linear indexing:

>> G = Start_Matrix([15;16;18;12;13;14])
G =
       78.808
       83.353
       112.37
        188.5
       233.06
       231.47
