Hmm, I don't think that's Laura's problem
(and actually I don't know what her problem is) :
Assignment of a 1 x 1

Hi

I've been trying to calculate the loglikelihood of a function iterated over
a data of time values and I seem to be experiencing difficulty when I use
the function expm(). Here's an example of what I am trying to do

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

I don't quite understand the question. The exponential of a matrix is
only defined for square matrices.
