Eigen - get a matrix from a map?

Question

I'm using Eigen::Map to get access to create an object from a C-array. I would like to save that object as a member variable of type MatrixXf. How do I do that? I couldn't find a way to convert the Map to a Matrix. Thanks.

Accepted Answer

Just use `operator=`:

```
MatrixXd mat;
mat = Map<MatrixXd>(data, rows, cols);
```
