#1307: Sparse matrices are limited to 2^32 non-zero elements

 Reporter:  peb                       |       Owner:  wnbell
     Type:  defect                    |      Status:  new   
 Priority:  normal                    |   Milestone:  0.9.0 
Component:  scipy.sparse              |     Version:  0.8.0 
 Keywords:  compressed sparse matrix  |  
--------------------------------------+-------------------------------------
 compressed.py in scipy.sparse creates arrays with a dtype = intc. This
 limits the size of a sparse matrix to 2^31 non-zero elements, preventing
 the solution of very large matrices.

 It is suggested that a keyword be added to allow these arrays to be
 created with other dtypes, such at uintc and uint64.
