Merging complicated small matrices to one big matrix

[Chengi Liu]

I have an rdd in pyspark which looks like follows:
It has two sub matrices..(array,array)

So, basically I  have sub matrices like [sub_matrix_1, sub_matrix_2.... ]
(the above has just two matrices..

I want to combine in one big matrix column wise

[ sub_matrix_1
 sub_matrix_2
....
]
Any suggestions?
