[vtkusers] vtkMath::LUFactorLinearSystem

[Adriano Gagliardi]

Dear All,

I'd like to use vtk's implementation of LU factorisation, but I am not sure
how to prepare the type of argument it requires. The function header is:

int vtkMath::LUFactorLinearSystem( double **A, int *index, int size, double
*tmpSize );

The issue is the first argument, double **A, which I believe is a list of
pointers to pointers to doubles? Is this correct? Can someone provide an
example of how to construct this so that it could be used as input into the
function, please?

Regards,

Adriano
