Use

<<LinearAlgebra`


BlockMatrix[arr]


or 

<<ImageProcessing`

MatrixJoin[arr]


where arr is your partitioned data

How do you unpartition a matrix?

For example: Starting with, 

Partition[Table[4*(i - 1) + j, {i, 4}, {j, 4}],{2,2}]


how do you go back to,

Table[4*(i - 1) + j, {i, 4}, {j, 4}]
