  "abstract": "This is the last one of three successive articles by the authors on matrix-weighted Besov-type and Triebel--Lizorkin-type spaces $\\dot B^{s,\\tau}_{p,q}(W)$ and $\\dot F^{s,\\tau}_{p,q}(W)$. In this article, the authors establish the molecular and the wavelet characterizations of these spaces. Furthermore, as applications, the authors obtain the optimal boundedness of trace operators, pseudo-differential operators, and Calder\\'on--Zygmund operators on these spaces. Due to the sharp boundedness of almost diagonal operators on their related sequence spaces obtained in the second article, all results presented in this article improve their counterparts on matrix-weighted Besov and Triebel--Lizorkin spaces $\\dot B^{s}_{p,q}(W)$ and $\\dot F^{s}_{p,q}(W)$. In particular, even when reverting to the boundedness of Calder\\'on--Zygmund operator on unweighted Triebel--Lizorkin spaces $\\dot F^{s}_{p,q}$, these results are still better.",
