[R] avoiding loops in equation

To illustrate my problem, I have a complex code of several matrices and a vector. To simplify I only used two matrices and a vector as an example: pex<-function(acc, pga, std){ (acc-pga)/std } acc<-seq(.1,1,.1) pga<-matrix(rnorm(9,4,.1),3,3) std<-matrix(rnorm(9,4,.5),3,3) I tried calculating
