I have a variable std::vector<std::vector<float>> I want to pass this variable to a function which accepts array of array of float **float. I was wondering if there is any way to do this?

Each vector should have raw pointer to its data `.data()` but without more information it is hard to tell – Killzone Kid Mar 19 '18 at 17:42

`array of array`, like a raw `float array[][];`? – Drise Mar 19 '18 at 17:43

6If you already have a vector then you should stay away from the arrays and pointers. – Ron Mar 19 '18 at 17:43

1Not a duplicate, in my opinion. The dupe shows that a vector is an array, behind the scenes. That doesn't work with a vector of vectors. – Drew Dormann Mar 19 '18 at 17:44

1@tadman Write a wrapper around old libraries. – Drise Mar 19 '18 at 17:44

5@Drise True, but to do that you need to solve this conversion problem first, so we're right back to the original question. – tadman Mar 19 '18 at 17:45

2Show us the signature of function in question. – SergeyA Mar 19 '18 at 17:46
