cosine similarity for vector and matrix

[huashan]

Thank you for this great package. It's super fast for computing cosine similarity for matrix pairwise. I'd like to ask if its possible to compute cosine similarity between a vector and each row/column of a matrix and keeping the efficiency? Yes, lapply() would do the work but way too slow comparing with proxy::simil()

same here, could also use a function like that if there are any efficiency gains to be had compared to looping/applying
