Suppose that we wish to find the sum of the absolute value of all even-indexed components in a vector. For example, if x = [11, 12, 13, 14], the result would be |22| + |14]. We will use linear programming to achieve such a goal. Assume the desired variable is t = [tı,t2]7. In order to use the MATLAB lpsolver(), we need to define a vector c, a matrix A, and another vector b, such that our problem be- comes: min c .t TER2 subject to At
