I don't know what your question is; however, it is unlikely that you
want the //MatrixForm as part of the definition of A1. You should use
parentheses to separate the formatting from the definition.

(A1 = {{-1/2*S22*\[Chi]^2 + I*a21*\[Chi],
     I/(2*\[HBar])*\[CapitalDelta], -I/(2*\[HBar])*\[CapitalDelta],
     0}, {I/(2*\[HBar])*\[CapitalDelta],
     2*S12/\[HBar] - S22*X^2/2 - 2*S11/\[HBar] -
      I*\[Epsilon]/\[HBar] - 2*I*\[Lambda]/\[HBar],
     0, -I/(2*\[HBar])*\[CapitalDelta]}, {-I/(2*\[HBar])*\
\[CapitalDelta],
     0, -2*S12/\[HBar] - S22*X^2/2 - 2*S11/\[HBar] +
      I*\[Epsilon]/\[HBar] + 2*I*\[Lambda]/\[HBar],
     I/(2*\[HBar])*\[CapitalDelta]}, {0, -I/(2*\[HBar])*\
\[CapitalDelta],
     I/(2*\[HBar])*\[CapitalDelta], -1/2*S22*\[Chi]^2 +
      I*a21*\[Chi]}}) // MatrixForm
