Hi Folks,
This loop code is working fine but I would like to simplify it further. Can anyone help?
Basically, i need syntax to automate the row definitions of k, SE_ans and A, the columns are fine I think.
k is a 3*3 matrix, SE_ans is a 3*1 vector, A is a 3*3 identify matrix. The rests are just constants.
for i=1:size(k,1)
k(1,i)=subs(SE_ans(1,:),[theta_1, theta_2, theta_3, k_t1,k_t2,k_t3],[A(i,1), A(i,2), A(i,3),1,2,3])
k(1,i)=subs(SE_ans(1,:),[theta_1, theta_2, theta_3, k_t1,k_t2,k_t3],[A(i,1), A(i,2), A(i,3),1,2,3])
k(1,i)=subs(SE_ans(1,:),[theta_1, theta_2, theta_3, k_t1,k_t2,k_t3],[A(i,1), A(i,2), A(i,3),1,2,3])
k(2,i)=subs(SE_ans(2,:),[theta_1, theta_2, theta_3, k_t1,k_t2,k_t3],[A(i,1), A(i,2), A(i,3),1,2,3])
k(2,i)=subs(SE_ans(2,:),[theta_1, theta_2, theta_3, k_t1,k_t2,k_t3],[A(i,1), A(i,2), A(i,3),1,2,3])
k(2,i)=subs(SE_ans(2,:),[theta_1, theta_2, theta_3, k_t1,k_t2,k_t3],[A(i,1), A(i,2), A(i,3),1,2,3])
k(3,i)=subs(SE_ans(3,:),[theta_1, theta_2, theta_3, k_t1,k_t2,k_t3],[A(i,1), A(i,2), A(i,3),1,2,3])
k(3,i)=subs(SE_ans(3,:),[theta_1, theta_2, theta_3, k_t1,k_t2,k_t3],[A(i,1), A(i,2), A(i,3),1,2,3])
k(3,i)=subs(SE_ans(3,:),[theta_1, theta_2, theta_3, k_t1,k_t2,k_t3],[A(i,1), A(i,2), A(i,3),1,2,3])
end
thanks

Isn't it straight forward
tmp1 = [theta_1, theta_2, theta_3, k_t1,k_t2,k_t3];
for ii=1:size(k,1)
tmp2 = [A(ii,1:3),1,2,3];
for jj=1:size(k,2)
code
end
end
I guess I missed the point
