R help - Dec 2009 - Matrix to list object

let consider following matrix :

mat <- matrix(rnorm(45), 15)

Now I want  to convert it to a list object "mat_list", which will have
15
elements and each element will again be a matrix with 3 rows and 3 columns.

How can I do that?

Thanks,

Try this:

mat_list <- lapply(split(mat, seq(nrow(mat))), matrix, ncol = 3)
