BoxMatrix

BoxMatrix

gives a matrix of s.

gives a block of s centered in a w×w matrix of s.

BoxMatrix[{r₁,r₂,…},…]

gives a array of s.

Details

BoxMatrix[r] gives a square pattern of s extending r positions from the center.
The parameter r need not be an integer; elements are if their chessboard distance from the center is not more than |r+1/2|.
BoxMatrix[All,w] gives a w×w matrix containing a box shape that is as large as possible.
BoxMatrix[…,{w₁,w₂,…}] gives a w₁×w₂×… array.
BoxMatrix[{r₁,…,r_n},w] gives a w×…×w array.
BoxMatrix[All,{w₁,…,w_n}] gives a w₁×…×w_n array containing a box-shaped region that is as large as possible.

Scope (4)

Put a box inside a bigger matrix:

Extend the box to the boundaries of the matrix:

Automatically choose a width to just fit the box matrix:

Extend the box to the given width, and automatically choose the height:
