How can I put a leaf right next to the flower in this code?
n=800;
r=linspace(0,1,n);
theta=linspace(0,2*pi,n);
[R,THETA]=ndgrid(r,theta);
% define the number of petals we want per cycle. Violets have 5!
petalNum=5;
x = 1 - (1/2)*((5/4)*(1 - mod(petalNum*THETA, 2*pi)/pi).^2 - 1/4).^2;
% update the formula for phi to stop the spiralling effect
phi = (pi/2)*exp(-2*pi/(8*pi));
y = 1.95653*(R.^2).*(1.27689*R - 1).^2.*sin(phi);
R2 = x.*(R.*sin(phi) + y.*cos(phi));
X=R2.*sin(THETA);
Y=R2.*cos(THETA);
Z=x.*(R.*cos(phi)-y.*sin(phi));
% color code for blueviolet RGB 138,43,226
% Indigo rgb value (75,0,130)
mapSize=20;
blue_map=linspace(138,75,mapSize)';
blue_map(:,2)=linspace(43,0,mapSize)';
blue_map(:,3)=linspace(226,130,mapSize)';
% and a pretty bit in the middle
gold_map=[255 215 0; 250 210 0];
% combine to form a full flower map
violet_map=[gold_map; blue_map];
% Now lets plot it and try and pick an attractive angle
surf(X,Y,Z,'LineStyle','none')
colormap(violet_map/255)
view([-12.700 81.200])

Neither do we. We'd have to figure it out just like you'll have to. It's not obvious plus there are an infinite number of ways the leaf could look like. Good luck though.
