[Clp] Need a pointer

Tue Mar 24 05:05:05 EDT 2009

I couldn't find the documentation, but from the SolveProblemBakery example, it seems clear.
The problem built is

C1:          0.1 * Sun + 0.2 * Moon <= 1400
C2:          1 * Sun                                 <= 8000
C3:                             0.2 * Moon      <= 5000

Thus, the matrixBegin of size (n + 1), where n is the # variables, gives the begin indices in the matrixValue array of the variables' constraint elements. As such, the matrixBegin[0] = 0, and matrixBegin[n] = # nonzeros

Hi All:
I am very new to this group, and I am probably asking something that has been responded to before. My apologies. (I did try the archives, but could not readily find an answer).

I want to describe a problem on the fly from my C++ code and call the solver as in the unitTest.cpp problem.  The arguments to CoinLoadProblem are all clear except for matrixBegin.  Is there any place that this has been described or explained?  What are the elements in matrixBegin?

TIA
Krish
