Let \(k\) be an algebraically closed field. The \(T_{44}\)--singularity is defined by \(R:=k[[X,Y]]/\langle F\rangle\;,\;F=XY(X-Y)(X-\lambda Y)\;,\;\lambda\in k\smallsetminus \{0,1\}\). For a wide class of Cohen--Macaulay \(R\)--modules the corresponding matrix factorizations are explicitly described.
