Why won't this code generate the graph I need? What am I missing?

Create a vector t of elements with values from 0 to 360 with a spacing of 3.6 degrees. Using the parametric equations, create two vectors x and y that contain x coordinates and y coordinates, respectively.

    function generateflower
    for t=0:3.6:360 
    x = ((1 + cosd(5*t))*cosd(t));
    y = ((1 + cosd(5*t))*sind(t));
    plot(x,y)
    end
  end

You are not following the instructions to "create two vectors x and y that contain x coordinates and y coordinates,"

When plot() is asked to plot a single point at a time, there is no line to generate. It only generates a mark if you configure a marker. For example you would have seen something if you had used

plot(x, y, '*')
hold on

Yup I read the instructions way wrong..

function generateflower
x=zeros(1,101);
y=zeros(1,101);
n=1;
for t=0:3.6:360
x(n) = ((1 + cosd(5*t))*cosd(t));
y(n) = ((1 + cosd(5*t))*sind(t));
n=n+1;
plot(x,y,'r--')
end
end

How does this look?

Put the plot after the loop.
