1. The problem statement, all variables and given/known data I am trying to run a model in matlab. D is a 2 by 3 matrix, Knowing that DL=0, which means L is mapped to the null space. 2. Relevant equations How can i find L so that it is a 3 by 3 matrix with all its entries being one times a scalar. 3. The attempt at a solution I used null(D) to find L, the solution is a 1X3 matrix (a vector). Since i want a three by three matrix, can i just say that L=[null(D), null(D), null(D)] since L is mapped to the null space(a zeros vector/matrix) thus does not matter if i extend it from a vector to a matrix anyways. Also, can i put an alpha in front of the L to ajust its value so that all its entries equal to 1?
