Do you have any attempts? What is the problem?

clc;
clear all;
close all;
a=1;
b=1;
R=5;
teta=a/R;
theeta=-teta:0.01:teta;

for i=1:length(theeta)
    x(i)=R*sin(theeta(i));
    z(i)=R*cos(theeta(i));
end
z = repmat(z,length(theeta),1);
y=0:1/40:1;
for i=1:length(x)
    for j=1:length(y)
    z(i,j)=z(i,j);
    end
end
surf(x,y,z);

@Twinkle C M I formatted your code using the text-code toggle; please format your code in the future to increase your chances that people will want to read the question/comment.

I also added a semicolon in this line so the command window isn't flooded with outputs: z(i,j)=z(i,j); & z = repmat...

If you add

axis equal
view(30,15)

and change the surf command to

surf(x,y,z, 'faceColor', 'flat','LineStyle', 'none');

you get close to what you want. You may need to increase the width (z).
