I have a piece of numpy code.

Code: Select all

distance = np.ones((N,)) * 1e10
         mask = dist < distance     
        distance[mask] = dist[mask]

l think the distance and dist is a matrix or a vector.through comparing the value of distance and dist,I want to find a smaller value and store that in distance.
In c++,I can only do this with a for loop.Does eigen have a wrapped function to implement this operation.thank!!

"select" function can do it.
