    Reading a Large Library or Program

    I like to look at source code whenever I can, but I can never figure out where to start. Obviously, the first step is to find main and then read on from there. Libraries are a different story, and I...

    Re: Metaprogramming Nested Loops?

    OK, I will file a bug report. It's not the multiplication that is messed up. It is multiplying and assigning. Not with the *=, but with the example above (I hope I am remembering this right. If I...

    Re: Metaprogramming Nested Loops?

    Are you saying it would be better for me to extend the blitz++ library. It cannot handle some things that it should be able to handle. Last time I use it, it produced odd results with things like (I...

    Metaprogramming Nested Loops?

    Re: how to reverse a doubly link list??

    luh@r PTR_XOR is a macro. It takes in two values a and b. It type casts a and b to integers and the XOR's them together. It then converts that value back to a pointer of type void*. Macros are nice...

    Re: Template function not generated?

    I suppose there is only one solution then. That is to add another template argument (maybe a couple because of other things I will be using the class for). Here's what I came up with (I'm not sure if...

    Re: Template function not generated?

    Dope, dumb mistake. I know exactly what is happening now. The template is actually generating the function for Vector::iterator. It then looks to find Vector::iterator::iterator. It gets confused and...

    Re: List Class

    The list class is designed to keep you away from raw access to pointers (That's why iterators were invented). The other problem you face is that when a list is updated the iterators become...

    I figured it out! What it does is in the operator= overload for TinyMatrix it returns an object that has operator,(T_numtype) overloaded. That object takes as an argument an iterator to TinyMatrix....
