# I need to write down a function 'linzav' which needs to check is the given set of vectors linearly dependent or independent. If it is dependent, write down one vector as linear combination of others?

A way to start might be something like this:

Vec_1=[1;2;3]

Vec_2=[2;4;6]

Lin=Vec_1./Vec_2

if all(Lin == Lin(1))

disp('linear')

end

So what this code actually does: You first create two vectors (which are of course linear dependent). If you devide one by the other, all elements should be the same if they are linear dependent. The "if" checks if all elements of the linear-resolution are the same. Sorry for my bad english. I hope this helps you to start with the program.
