SSKYMM/DSKYMM/CSKYMM/ZSKYMM

Skyline matrix-matrix multiply

 

upper triangular matrix (descra(2)=2). All entries from

 

the first nonzero entry through the diagonal entry of a

 

row (column) are stored.

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.
