Look at the first example in the documentation for 'for': https://www.mathworks.com/help/matlab/ref/for.html

Hi,
I want to creat matrices automatically with for loop in Matlab?
phi1=30; phi2=45; phi3=90;
After running the code I want to have a matric A with the following elements:
A=[sin(phi1) cos(phi1) sin(phi1)*cos(phi1);
sin(phi2) cos(phi2) sin(phi2)*cos(phi2);
sin(phi3) cos(phi3) sin(phi3)*cos(phi3);]

Thanks!
I want to use
for i=1:3
for j=1:3
A(i,j)=...;
end
end
I want shorter code.

I did it. I used for loop and function.
phi=[30, 45, 90];
n=length(phi);
[e]=xuat_vecto(phi1);
A=zeros(n,3);
for i=1:n
[d]= xuat_vecto (phi(i));
A(i,:)=[d];
end
A
function [e]=xuat_vecto(alpha)
[a, b, c]=ham_luong_giac (alpha);
e=[a, b, c];
end
function [a1, a2, a3] = ham_luong_giac (phi)
a1=sin(phi);
a2=cos(phi);
a3=sin(phi)*cos(phi);
xuat= [a1, a2, a3];
end
