# 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.

# 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,,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.

## Basic Examples(1)

This computes and plots a box:

## 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:
