For example if I have the vector x=[1 3 7 9] and I need two split it into y=[1 3] and z=[7 9]. If the right-hand side is not a square matrix as is the case here, it is solved using least-square method. rev2022.11.14.43031. If you want to have to arrays with the same length you should use numel() or size() to get the size and then take half of it. The best way to deal with vectors is to work in a vector space. Obviously we can define something similar, as we can define multiplication pointwise of vectors. Can I say something.In matrices (2x1)/(2x1)=(2x2) we can say this because If we want to control that we must multiply (2x2)x(2x1) and we get (2x1) so I understand that a/b question's answer is two vector system.Can we say this ?

If the vector contains an odd number of elements, the middle element may become a part of either vector. A = ( 1 0 0 0 1 0) then the output A x is going to be the smaller vector A x = ( 3, 1). This becomes which is . For the calculation of vector division here we use the division(/) operator. If we print 1:10, we see after we execute this, that actually just creates a vector of 10 numbers.
