Dear All,

I'm new to Eigen and I'm not sure whether my question has been mentioned yet. Here's my question:

I have a dense matrix with positive and negative numbers. I want to set all the negative numbers to zero and create a sparse matrix based on it. I want to ask what's the best way or the most efficient way to do this? Shall I make two for loops?

Thanks! I really appreciate your help.
