Re: [eigen] How to resize a partially fixed matrix

[Benoit Jacob <jacob.benoit.1@xxxxxxxxx>]

First of all the variant proposed:

>> So I'm strongly for your code change, but changing the assertion to
>> EIGEN_STATIC_ASSERT_EXACTLY_ONE_DYNAMIC_DIM(Matrix)

doesn't make me comfortable, again because a method that works for
(partially)dynamic matrices should also work on fixed-size matrices of
the same size, I am very reluctant here.

So here's what I did (changeset b030f9866bae):
    * add resize(int, NoChange) and resize(NoChange, int)
    * add missing assert in resize(int)
    * add examples for all resize variants
    * expand docs (part of which is from Tim Hutt's e-mail)

Now if you want we can add another name (or completely rename) the new
resize(int, NoChange) and resize(NoChange, int).
But perhaps it's good enough like this? i don't have a strong opinion.
resizeHoriz(size) and colwise().resize(size) look nice but they aren't
much shorter to type than resize(NoChange,size);

Cheers,
Benoit
