I have seen examples of items added but not accessed/indexed.

Hi,

one your CPLEX matrix is built you may use

c.linear_constraints.set_linear_components("c1", [["assign_1_1"], [1.0]]);

in order to edit an item

Hi  Alex,

Thanks for your help. So the .__getattribute__('ind'), .__getattribute__('val'), .__getattribute__('names') seems to work for SparsePair so I am actually able to access and based on the sparse pair indexing.

Thanks for your help!
