SELLSM/DELLSM/CELLSM/ZELLSM Ellpack format triangular solve
val( ) Two dimensional lda-by-maxnz array such that val(i, :)
consists of nonzero elements in row i of A, padded by
zero values if the row contains less than maxnz.
lda Leading dimension of val and indx.
indx( ) Two dimensional integer blda-by-maxnz array such
that indx(i, :) consists of the column indices of the
nonzero elements in row i, padded by the integer value
i if the number of nonzeros is less than maxnz.
maxnz Max number of nonzero elements per row.
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. lwork should be at least
mb x lb x min(lb, n).
lwork Length of work array.
