Abstract: In this article, we exhibit explicitly the matrix model ($\ensuremath{\theta}=\ensuremath{\infty}$) fixed point of ${\ensuremath{\phi}}^{4}$ theory on noncommutative spacetime with only two noncommuting directions, using the Wilson renormalization group recursion formula and the $1/N$ expansion of the zero-dimensional reduction, and then calculate the mass critical exponent $\ensuremath{\nu}$ and the anomalous dimension $\ensuremath{\eta}$ in various dimensions.
