Write a function drawBox which draws boxes on the screen. The function is called with a character (ch) as the first argument and two positive integers which represent the width and the height of the box to be drawn. It automatically draws a box with the character (ch) by the specified width and height.

for example : drawbox('A';10;6)

['A' repmat( ' ', [1 8] ) 'A']

can produce one of the central lines. The top and bottom lines are even simpler. Then you just have to work out how to put it on the screen and use the input arguments rather than hard-coding numbers in.
