hi i'm trying to plot this function and get the same result from the book
the function:![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1142370/image.png)

the plot in the book; ![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1142380/image.png)

this is my code
i need to find a way to make the plot smother
c=1
for k=1.2:0.4:2.8
u=linspace(0,2.8,5)
u1=0:0.01:2,4
f=(k/c).*(u/c).^(k-1).*exp(-(u/c).^(k))
plot(u,f)
hold on
end

c = 1;
k = 1.2:0.4:2.8;
u = (linspace(0,2.4,100)).';
f = (k/c).*(u/c).^(k-1).*exp(-(u/c).^(k));
plot(u,f)

I believe Torsten's solutions solves your issue, but I wanted to comment to let you know you should avoid using for-loops when possible. Matlab is much quicker at processing vectos and matrices, and in many case, you can take advantage of GPU computing for large amounts of data.
