In this work we considered the matrix decomposition of the cubic irrational $\alpha$ satisfying the equation $$x^3 - 4x^2 - 5x - 1 = 0.$$ For decomposition of the matrix $$ \left( \begin{array}{c} \alpha \\ 1 \\ \end{array} \right)=\prod_{k=0}^\infty\left( \begin{array}{cc} 310941\cdot k+155427 156744\cdot k+78333 \\ 61578\cdot k+30882 31041\cdot k+15564\\ \end{array} \right) $$ an algorithm of transition to regular continued fraction is constructed. Bibliography: 2 titles.
Keywords: continued fraction, matrix decomposition, reduced cubic irrational, algorithm of transition from matrix decomposition to continued fraction.
