hesv_driver_grp(3)

💅 hesv_driver_grp(3)

okay so this is one of those pages from the LAPACK manual — Library Functions Manual energy — and bestie, it's a whole group page, not a single function. It's the landing spot for the LDL driver collection: Hermitian/symmetric indefinite matrices, driver routines only. Think of it as the group chat where all the {he,sy} and {hp,sp} girlies live 🫶

✨ NAME ✨

hesv_driver_grp — LDL: Hermitian/symmetric indefinite matrix, driver 👑

literally what it says on the tin: this is the driver tier for LDL-style factorizations of Hermitian/symmetric indefinite matrices. no cap.

🌸 SYNOPSIS 🌸

🎀 Topics 🎀

the routines are organized into little cliques, and yes they each get their own intro. here's the roster, exactly as listed:

— full, rook pivoting —

• {he,sy}sv: rook (v1) 🧚
• {he,sy}sv_rook: rook (v2) 🧚
• {he,sy}sv_rk: rook (v3) 🧚
• {he,sy}svx: rook (v1, expert) 💅
• {he,sy}svxx: rook (v1, expert) 💅

— packed, rook pivoting —

• {hp,sp}sv: factor and solve 🔥
• {hp,sp}svx: factor and solve, expert 🔥

— full, Aasen —

• {he,sy}sv_aa: Aasen ⭐
• {he,sy}sv_aa_2stage: Aasen, blocked 2-stage ⭐

quick vibe check on the naming, iykyk: {he,sy} means the Hermitian and symmetric versions are twins, and {hp,sp} is the packed-storage counterpart of that same duo. the suffix tells you which algorithm and which tier — plain, _rook, _rk, x, xx, _aa, _aa_2stage. don't mix them up bestie, they are not interchangeable 😭

🦋 Detailed Description 🦋

so the "Detailed Description" section here is, um. empty. like, genuinely nothing under it in the source 🫠 this page is purely a container that gathers the topic groupings above — the actual tea is in each individual routine's own page. go click through the list, that's where the real content lives ✨

not a human, not a vibe curator, just Doxygen doing its thing 🙈 the prose you're reading right now? that's me. the page structure? that's the robot.

mwah 💖 go forth and factor your indefinite matrices, bestie — full or packed, rook or Aasen, plain tier or expert tier, the whole family's here for you 🌈
