i want to store the values of bold part for each iteration of i.

for i=1:3

for j=1:10

for k=1:10

x3(j,k)=X3(i)+p;

y3(j,k)=Y3(i);

p=k*l;

end

p=0;

Y3(i)=Y3(i)+l;

end

end

I don't understand. The right hand size of the equations are being saved into little x3 and little y3 matrices. Of course you're overwriting for each iteration of i, so maybe you want three indexes:

for i=1:3
    for j=1:10
        for k=1:10
            x3(i, j, k) = X3(i) + p;
            y3(i, j, k) = Y3(i);
            p=k*l;
        end
        p=0;
        Y3(i) = Y3(i) + l;
    end
end

What are your initial X3 and Y3 vectors?

What are the values of p, and l ("ell")?

Do you want x3 and y3 to be 3-D arrays where each 2-D plane is just one plane of the 3-D array?

Try this:

p = 0;
l = 2;
X3 = [-7.655; -6.189; -3.251]
Y3 = [1.393; 10.42; 6.639]
x3 = zeros(10, 10, 3);
y3 = zeros(10, 10, 3);
for plane = 1:3
    for j = 1 : 10
        for k = 1 : 10
            x3(j, k, plane) = X3(plane) + p;
            y3(j, k, plane) = Y3(plane);
            p = k * l;
        end
        p = 0;
        Y3(plane) = Y3(plane) + l;
    end
end
x3
y3
