I have to agree. If the goal of MTL3 is relatively high performance then
vector/matrix resizing is probably not a good idea. On the other hand one of
the powerful and useful aspects of Matlab, for example, is the dynamic
matrix/vector resizing.
Could we not have a template specialisation, or something, that might allow
for vector resizing in the future, at least.
For example, I'm imagining something like:
Vector<float, nonresizeable> a;
Vector<float, resizeable> b;
I have found resizeable vectors and matrices useful in modified nodal
analysis circuit simulation where you don't know before analysing the
circuit graph how large the system of equations is. Once the circuit is
analysed and you are about to simulate the system of equations is static and
at that point it would be useful to have nonresizeable vectors for
computational efficiency.
