Optical Transfer Function 3D Mesh

Hi everyone, I am new to matlab coding and need some help!!

I am attempting to make a 3D mesh from the code below, however I am keep getting error codes!

p=(0:0.01:1);

plot(p,H)

title('Optical Transfer Function')

xlabel('x')

ylabel('H')

legend('H VS x')

[X,Y] = meshgrid(0:0.01:1);

mesh(X,Y)

Try this:

[X,Y] = meshgrid(-1:0.01:1);
R = sqrt(X.^2 + Y.^2) + eps;
Z = (2/pi)*((acos(R))-(R).*sqrt(1-(R).^2));

figure
mesh(X, Y, abs(Z))
grid on

then modify the code to get the plot in the image, for example:

Z = (2/pi)*((acos(R))-(R).*sqrt(1-(R).^2)) .* (R <= 1);

Experiment to get the result you want.
