A given transfer polynomial can have several possible regions of convergence in this problem you will write a function possibleroc that enumerates the possible ROCs for a transfer function with given denominator. Your function should accept one input di a row vector of coefficients of the denominator polynomial. The first element corresponds to the highest order coefficient, the last element corresponds to the oth order coefficient (ie the constant term). and return one output . rocs: a sorted N X 2 matrix of possible ROCs, specified by their left and right edges, where N is the number of unique ROC's. The rocs matrix should be sorted as follows: Each row of rocs should contain a unique region. The possible ROCs should be ordered from left to right along the real axis, such that the leftmost region is in the first row of rocs and the rightmost region is in the last row. The first column should contain the left boundaries for each RoC, the right columns should contain the right boundaries. For example, if a given row of rocs has value [2.5), that would correspond to the ROC: 2
