Basically I want to construct the following cyclic matrix M = where the elements are pointers to a 1D Mat v = (a b c) Such that whenever I change a value in the vector the matrix is then updated accordingly, and I can multiply the matrix M with another matrix for instance. Am I supposed to use something like Ptr<mat> to initialise M? And how do I assign pointers to this matrix? I'm using C++. Best Al |
