Long story short: int const M = 3;
I have checked the link already. Yes, I had tried that it worked, but, as I said the dimensions are going to be read from a file given by the user (that is run time I guess). That means that Boost can not let the user apply a desired dimension?
It's not really about Boost. It's about understanding the fundamentals of templates. They are instantiated at compile-time, and instantiations with distinct parameters are distinct types. If you want to make a runtime choice based on a runtime count, you need to either have instantiations of the template for each and use a wrapper that applies sufficient type erasure/hiding, or you would have to have a type that has runtime-parametricism in dimensions. If your question is: "does this library have a type with runtime-configurable dimensionality" and "can I use that type with the algorithms", you should probably ask _that_ question instead. -- Lars Viklund | zao@acc.umu.se
