DemandVectorSP.sparse

DemandVectorSP.sparse(dtype=None) → scipy.sparse.csc.csc_matrix

Get demand as sparse matrix.

Total in/outflow per node (row) per commodity (column), e.g.,:

Data:

(0, 2, 100)
(3, 1, 66)

Resulting matrix:

[[-100,    0],
 [   0,   66],
 [ 100,    0],
 [   0,  -66]]

Parameters

dtype: dtype, optional

Datatype of returned sparse matrix.

Returns

scipy.sparse.csc_matrix

Demand as sparse matrix.
