Hi Everybody, I am newbie to core.matrix .. I have the following expression
W -> a large spare matrix of size MxN U -> a dense matrix of size MxK V -> a dense matrix of size KxN and K << (M,N) (require [clojure.core.matrix :as m]) I want to compute (m/mul W (m/* U V)) m/mul computes element-wise product m/* computes regular matrix multiplication I want to know if the above would compute full-matrix UV .. if it does then I want to know if there is an elegant way to compute the spare-resultant matrix without blowing up memory in the intermediate stage I am currently just extracting the corresponding rows and columns from U and V for the elements which are non-zero in W .. but that seems unnecessarily verbose... I am using the vectorz implementation of core.matrix Thanks in advance. Sunil. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
