typo in vector container concepts documentation

[dougrm@…]

In the second table of http://www.boost.org/doc/libs/1_37_0/libs/numeric/ublas/doc/container_concept.htm#vector, the phrase:

array_type& if a is mutable

should read:

array_type& if v is mutable

[dougrm@…]

Actually, the entire line of the table is messed up. Under "Type requirements", it says:

v is mutable and Dense.

Under "Return types" it says (with v replacing a):

array_type& if v is mutable, const array_type& otherwise

But v is required always to be mutable so the otherwise case makes no sense. The type requirement should be just that v is dense.

The corresponding line in the matrix concepts table has the same problems. Here, a has to become m (not v).

• fixed typos

• need still some time to think about the "is mutable" comment

The concepts for "immutable" and "mutable" classes will be handled in task #3188.
