I have x and y coordinates of a n*2n grid fixed grid. I have generated circular shape (circle.JPG) with
sqrt((x-cx).^2 +(y-cy).^2)-r, where (cx, cy) are the centre and r is the radius of the circle
I have generated elliptical shape (ellipse.JPG) with
((x-cx)/a).^2 +((y-cy)/b).^2)-1, where (cx, cy) are the centre and a is the horizontal radius and b is the vertical radius of the ellipse
I need a code that can generate each of the following shapes in the picture (Picture_1.jpg).
Thank you so much.

Try this:
period = 10;
amplitude = 4;
offset = 6;
x = linspace(0, 40, 700);
y = amplitude * cos(2 * pi * x / period) + offset;
plot(x, y, 'b-', 'LineWidth', 2);
grid on;
ylim([0, amplitude + offset]);
For the triangle wave, use sawtooth() or repmat(). I'm sure you can figure it out because you're a smart engineer.
