Convert vectors to column matrices for some matrix operations.

[dpvc]

For the MatrixReal1 macros that require column vectors, convert vectors to column matrices. This is for normalize(), solve_LR(), and other solve macros.

To check, use

TEXT(join(', ',Matrix([1,2],[3,4])->normalize(Vector(1,2))));
TEXT(join(', ',Matrix([1,2],[3,4])->solve_LR(Vector(1,2))));

Without the patch, these will throw errors. With the patch, they should succeed.

This passes the tests.
