# BoxMatrix

 BoxMatrix[r] gives a × matrix of s. BoxMatrix[r, w]gives a × block of s centered in a w×w matrix of s. BoxMatrix[{r1, r2, ...}, ...]gives a array of s.
• 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, ..., rn}, w] gives a w×...×w array.
• BoxMatrix[All, {w1, ..., wn}] gives a w1×...×wn array containing a box-shaped region that is as large as possible.

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:
