Can the expm function be used to calculate the exponential of a matrix where
the matrix is multiplied by a vector in a data frame?
For example
for (i in 1:length(y)){
expmN<-expm(Q*y[i])
Q<-Matrix(c(1, 2, 3, 4), 2, 2)
return(expmN)
}
Sorry I am new to R and I have been finding it difficult to get information
on calculating Matrix exponentials in R.
Many thanks in advance
