Ahmed, The file and the respective classes were deleted in https://github.com/dealii/dealii/pull/9761 and deprecated in https://github.com/dealii/dealii/pull/5352. If you need to replace BlockMatrixArray, you should have a look at the documentation in the latter pull request to use BlockLinearOperator( https://www.dealii.org/current/doxygen/deal.II/classBlockLinearOperator.html) instead.
