To ensure that a macro works as expected after the macro has been created and assigned a button or menu item, it should be ________

This problem is about graph signal inpainting via total variation regularization. Signal in- painting is the process of estimating missing signal values from available noisy measurements. Assume that the observed graph signal is y = [ y T1 y T2 ] T , where y 1 ? R M × 1 is known and y 2 = 0 ? R ( N ? M ) × 1 is missing or unknown. Now two cases are possible: the known part of the signal y 1 may be noisy or noiseless.

(a)



(b)

Hint: Use the method of Lagrange multipliers.

Note: The problem in the book has a small error. Above is the corrected version.
