A command to draw a Matrix object into the Picture window.
For every element of the Matrix inside the specified windowing domain, an opaque white or black rectangle is painted (white if the value of the element is positive, black if it is negative), surrounded by a thin black box. The area of the rectangle is proportional to the value of the element.
If you prefer the sides of the rectangle (instead of the area) to be proportional to the value of the element, you can use the formula "self^2
" before drawing (see Matrix: Formula...).
