CyLP.cy.CyCoinPackedMatrix

class CyLP.cy.CyCoinPackedMatrix.CyCoinPackedMatrix

CyCoinPackedMatrix interfaces CoinPackedMatrix

Usage Example

>>> import numpy as np
>>> from CyLP.cy import CyCoinPackedMatrix
>>> rows = np.array([1, 3, 4], np.int32)
>>> cols = np.array([0, 2, 1], np.int32)
>>> elements = np.array([1.5, -1, 2])
>>> # colOrdered is True if we store the matrix by column (csc)
>>> m = CyCoinPackedMatrix(colOrdered=True, rowIndices=rows,
...                           colIndices=cols, elements=elements)
>>> m.majorDim
3
>>> m.minorDim
5
