Auxiliary systems for matrix nonisospectral equations, including coupled NLS with external potential and KdV with variable coefficients, were introduced. Explicit ( up to the inversion of finite matrices) solutions of nonisospectral equations were constructed using the GBDT version of the Backlund-Darboux transformation.
