Fat Matrix Diagonals
fatdiag set
fatdiag(x = 1, steps = NULL, size = NULL, nrow = NULL, ncol = NULL) fatdiag(x, steps = NULL, size = NULL, on_diagonal = TRUE) <- value
x |
a matrix where the dimensions are integer multiples of size or integer dividors of steps |
steps |
the required number of steps (block matrices) across the diagonal |
size |
the width or height of the matrix being dropped over the diagonal of matrix x |
nrow |
the number of rows |
ncol |
the number of columns |
on_diagonal |
should the operation be applied to the elements on the fat diagonal. |
value |
replacement value |
Either steps or size is expected to be provided.
