    Change solver_output from 2-D to 1-D array · b4141be4
    Tjerk Vreeken authored
    Most arrays like lbg/ubg/x0 are already 1-D NumPy arrays if they are not
    a CasADi matrix (MX/DM). It therefore makes sense if the output of the
    solver is also a 1-D array, requiring only a single index to be
    specified to get an element (instead of X[i, 0]).
    We ensure that the results dictionary does not present views onto the
    raw solver_output by making a full copy of it first. This is just a
    safeguard though, as it is undefined behavior what should happen if
    someone changes the arrays in the results like that.
    Contrary to the previous type annotation, the solver output was already
    a numpy array (a 2-D one, see commit 40875b0a).
    Closes #1064
