(a) Consider the matrix of active constraints Aa=04610208503424377253. Use mysolve.m to construct a direction p along which the residual of the third constraint increases, but all the other residuals remain the same. If the rows of Aa are labeled 1 through 4 , what are the indices of the active set after a positive step along this direction? (b) Repeat part (a) for the vertex Aa=09033813114530666560054533704542210. Comment on your results. Is the vertex degenerate or nondegenerate
