Hi,

Is there a function for raising a matrix to a power? For example if you like to compute A%*%A%*%A, is there an abbreviation similar to A^3?

Atte Tenkanen

> A=rbind(c(1,1),c(-1,-2))
> A
  [,1] [,2]
[1,]   1   1
[2,]  -1  -2
> A^3
  [,1] [,2]
[1,]   1   1
[2,]  -1  -8

But:

> A%*%A%*%A
  [,1] [,2]
[1,]   1   2
[2,]  -2  -5
