pntr( ) Array of length m+1 (A lower triangular) or k+1 (A
upper triangular) such that pntr(i) and pntr(i)+1-1,
respectively, point to the location in val of the first
entry and last entry of the Skyline profile in row
(column) i. In any case, the last entry is the diagonal
entry.
b( ) Rectangular array with leading dimension ldb.
ldb Leading dimension of b.
beta Scalar parameter.
c( ) Rectangular arrary with leading dimension ldc.
ldc Leading dimension of c.
work( ) Scratch array of length lwork. Not used.
lwork Length of work array.
