I am trying to code in MATLAB the equations of motion for malankovich orbitlal elements. But, I am having a problem with the B matrix. Since f matrix is 7x1 and a_d matrix has to be 3x1, the B matrix has to be 7x3. I don't know how that is possible. Can you break down the B matrix for me and let me know what size it is?
I am trying to code the solution to the problem in the image in MATLAB. I wanted to know what is the milankovich constraint equation that is talked about in part b.
