WebI am uncertain on how the matrix that I am taking that value with respect to changes it. The exact equation I am considering here is: f ( q t + 1) = q t + 1 − q t w 2 + y t + 1 ∗ − ϕ ( q t) C 2. Which, when minimized gives the optimal joint command q t + 1 for a robotic arm moving to the coordinates y ∗. http://www.ece.northwestern.edu/local-apps/matlabhelp/techdoc/ref/norm.html
