We summarize how to describe D-branes in a matrix theory based on unstableD-instantons, which we call K-matrix theory, and explicity show that D-branescan be constructed as bound states of infinitly many unstable D-instantons. Weexamine the fluctuations around Dp-brane solutions in the matrix theory andshow that they correctly reproduce fields on the Dp-brane world-volume.Plugging them into the action of the matrix theory, we precisely obtain theDp-brane action as the effective action of the fluctuations.
