review text: The problem of almost periodic factorization of matrix functions of the form \[ \left[\begin{matrix} e^{i\lambda x} & 0 \\ f(x) & e^{-i \lambda x}\end{matrix} \right], \] \(f(x)= \sum^m_{j=1}c_je^{i\lambda_jx}\), is considered. The range of the spectrum of \(f\) for which factorability can be obtained is extended to several new classes unknown earlier.
