Extract every second value of a vector and write into a new vector
11 views (last 30 days)
Hi, another trivial question i guess - i'm a beginner at Matlab.
Xi = sym('Xi',[1,n2]);
I want to write the results into a new vector. I tried vertcat and some for loops but it didn't work out.
Here i get a result like (L1*Xi1, L1*Xi2, L1*Xi3, ...., L5*Xi1, ...., L5*Xi6) but i want to get (L1*Xi1, L5*Xi1, L1*Xi2, L5*Xi2, ...., L5*Xi6). Is there a trick when using vertcat or do i need to write a loop. I have the problem that BG has another dimension than the 2 vectors BGx and BGy. Thanks in advance

This is MATLAB so why use an ugly loop? MATLAB is much better than that! The code is simpler without it (I also got rid of sym: you don't say why you need it, and numeric operations will be much faster and more efficient):
>> X = [1,2,3,4];
>> L1 = 90;
>> L5 = 10;
>> Z = [L1+X;L5+X];
>> Z = Z(:)'
91 11 92 12 93 13 94 14
