Hi, All,
I'm using nalgebra DMatrix and want to assign a smaller dimension matrix y_1 to an equal-dimensional part (submatrix) of an existing matrix y. Maybe I missed the right section of the nalgebra documentation, but I can't find a better solution. The view_mut() method does not manipulate the matrix in-place and can't be used as the LHS in assignment operations. I can use fill_with() method for element-wise operations to do the job, but it is quite tedious and inefficient. I'm expecting an assignment statement like the view_mut() method:

y.view_in_place_mut((0,0), (m, n)) = y_1;

or

y.set_submatrix((0,0), (m, n), y_1);

where y_1 is an m*n matrix. Appreciate the assistance!
