Question

In Matlab:

Given the DrawRect function described in the lecture.

function DrawRect(a, b, L, W, c)

x = [a a+L a+L a a];

y = [b b b+W b+W b];

fill(x, y, c);

end

Which of the following function call will draw a black square with size of 10 by 10 with the center at (5, 0)?

a) DrawRect(0, -5, 10, 10, 'b')

b) DrawRect(5, 0, 10, 10, 'b')

c) DrawRect(0, -5, 10, 10, 'k')

d) DrawRect(5, 0, 10, 10, 'k')

Answer 1

Answer : c)DrawRect(0,-5,10,10,'k')
