Hello, I have the following problem: Given typedef mpl::vector_c<int, 3, 0, 3, 6, 9> MyVector; Now, I wish to create a mpl::vector with 3 entries that look like mpl::vector< mpl::vector_c<int, 1, 0, 3, 6, 9>, mpl::vector_c<int, 1, 1, 4, 7, 10>, mpl::vector_c<int, 1, 2, 5, 8, 11> > In words The first number in MyVector gives me the number of resulting vector_c types. the resulting types should contain a 1 instead of that number. The other numbers should be replace gradualy: The first vector_c should contain the same numbers as the original type. In the second vector_c, all the numbers should be incremented by one, and so forth. I have to admit, that this task overstrains me, so it would be very kind, if someone could help me to figure this out.
