How can I rotate an ellipse randomly

This is what I have written so far
t = linspace(0,2*pi)
x = randn + randn*cos(t)
rng('shuffle');
y = randn + randn*sin(t);
plot(x,y)
I want to create random rotation for this ellipse each time I plot it while keeping this same code I have written so far.

Well, that would be possible, but it would be significantly easier if you could modify your existing code to something like
t = linspace(0,2*pi)
xc = randn();
x = xc + randn*cos(t)
rng('shuffle');
yc = randn();
y = yc + randn*sin(t);
plot(x,y)
axis equal
If you do that then it becomes easier to rotate around its center, which would be at the known point (xc, yc). But if you insist that the existing code must be kept as-is, then it becomes necessary to estimate xc and yc
