Hello everybody.

Just a query (in fact two)

I have a reasonably huge matrix type data which is to be used via some other calculations, In the matrix are values of 1s, 0s and -1s which will appear in random and the actual i-jth position is important.

Is it any good to have a vector of pointers and will this be faster than some 'matrix' form?

the second query is about the best way (faster) you'd think to have matrix data stored. I've used

`vector<vector<double>>`

normally, This can be around C or C++ although i am using C++ at the moment.

Just a few sentences and a direction will suffice, examples are a bonus to me :)

Thank you in advance coders
