Usage

  mat_apply <- function(vec, fun)

Arguments

vec	vector of inputs fed into fun
fun	a function to call for each input of vec

Details

This function returns an array with first dimension of length(vec) provided length(vec) > 1–the first dimension indexes over the length(vec) outputs.

Examples

  # returns a 10 x 3 x 3 array. ret[i,,] contains i*diag(3).
  ret <- mat_apply(1:10, function(i){ i*diag(3) })
