WebMar 10, 2016 · 3 Answers. There are many ways to approach this depending upon your code, effort, and hardware. The simplest is to use crossprod which is the same as t (a)%*% b (Note - this will only be a small increase in speed) Use Rcpp (and likely RcppEigen / RcppArmadillo ). C++ will likely greater increase the speed of your code. WebJan 30, 2016 · Vectorization (as the term is normally used) refers to SIMD (single instruction, multiple data) operation. That means, in essence, that one instruction carries out the same operation on a number of operands in parallel. For example, to multiply a vector of size N by a scalar, let's call M the number of operands that size that it can …
