**What it does**

This tool stacks sparse matrices horizontally (column wise) or vertically (row wise).
It can handle two different formats:

 * Compressed Sparse Column matrix (csc_matrix)

 * Compressed Sparse Row matrix (csr_matrix)

Sparse matrices in column format should be stacked horizontally (hstack) , while matrices in row format are stacked vertically (vstack). This tool outputs a single resulting sparse matrix which is compatible with the inputs in format.    

**Parameters:** blocks sequence of sparse matrices with compatible shapes format.
