I believe you intended semicolons (;) instead of colons (:) in your matrix definition.

To convert it to a vector, use the reshape function:

Matrix = [1,1,1,1; -1,-1,-1,-1; 1,1,1,1];
Vector = reshape(Matrix', 1, [])
Vector =
       1     1     1     1    -1    -1    -1    -1     1     1     1     1

EDIT — Added output of ‘Vector’.
