Abstract: In the article, we compute the completely positive matrix numerical index of matrix regular operator spaces and show that they take values in the interval . Moreover, we show that the dual of a unital operator system has the completely positive matrix numerical index if its dimension is greater than . Furthermore, both and have the completely positive matrix numerical index if their dimensions are greater than , where , is a Hilbert space and is a finite von Neumann algebra.
