Explore the parent graph y=x^3 Experiment with the values of a, h, and k What happens to the graph as these values change?I will answer this way, since I suspect you're preparing for finals The x and y are the variables They aren't replaced with specific numbers in the equation unless you are finding (x, y) coordinates for points on the parabola The h is a horizonThe submatrix H i, j is of dimension P 2 × P 2 and represents the contribution of the jth band of the input to the ith band of the output Since an optical system does not modify the frequency of an optical signal, H will be block diagonal There are cases, eg, imaging using color filter arrays, where the diagonal assumption does not hold
