n-th power of a matrix

Hello all,
To calculate the power of a matrix, I used the command "mtx.exp(X, n)", 
but there is an error saying "Error: couldn't find function "mtx.exp"".  
How can I deal with this problem?

You have not told us in which package mtx.exp() is, and looking for it 
shows us that it is in package "Malmig".

  library(Malmig)
  mtx.exp(X, n)

works for me.


Folks, PLEASE think about the packages you are using!
