You can use linspace.
Example:
xData = linspace(0,4*pi,1024);
yData = cos(xData);
figure;
plot(xData,yData);

Knowing that the cycle length of a cosine wave is , what is the length of two cycles?
Once you know that, use linspace to generate a vector of 1024 points between 0 and that length. Pass that vector to cos and you're done.
