sc::SCMatrixBlockIter(3)

💅 sc::SCMatrixBlockIter — the manual, bestie edition 💅

Okay so real talk, this is the sc::SCMatrixBlockIter manpage from the MPQC manual, and honestly? It's giving "let me introduce you to my little iterator friend." No cap, it's actually so useful. Let's get into it. 🫶

✨ NAME ✨

sc::SCMatrixBlockIter — the vibes are: this class is used to describe iterators that loop through the elements in a block. Periodt. That's literally its whole personality. 💖

---

🌸 SYNOPSIS 🌸

Like, first things first, you gotta pull it in:

#include <blkiter.h>

And listen — it's inherited by a whole squad of subclasses. Not me listing them all but here we go:

• sc::SCMatrixDiagBlockIter
• sc::SCMatrixDiagSubBlockIter
• sc::SCMatrixLTriBlockIter
• sc::SCMatrixLTriSubBlockIter
• sc::SCMatrixRectBlockIter
• sc::SCMatrixRectSubBlockIter
• sc::SCVectorSimpleBlockIter
• sc::SCVectorSimpleSubBlockIter

It's giving main character energy with that many spin-offs, honestly. 👑

🎀 Public Member Functions 🎀

These are the moves, bestie. Every single one, no skips:

• virtual int i () = 0 — returns the row index. Slay. That's your row, bestie. 📍
• virtual int j () = 0 — returns the column index. Yes, column. We love a coordinate moment. 📍
• virtual void set (double val) = 0 — sets the current element to val. Iconic behaviour, honestly. ✨
• virtual void accum (double val) — adds val to the current element. It's not a set, it's an accum. Respect the distinction. 💅
• virtual double get () = 0 — returns the value of the current element. Obsessed. 🍓
• virtual operator int () = 0 — returns nonzero if there are more elements. Like, a vibe check: are we still iterating or are we done? iykyk. ⭐
• virtual void operator++ () = 0 — moves to the next element. Om nom nom, next please. 🦋
• void operator++ (int) — the postfix version. Hey, don't sleep on it just because it's not pure virtual. 🌈
• virtual void reset () = 0 — starts the iteration over. It's giving second chances, and honestly? We love a reset era. 💜

🦋 Detailed Description 🦋

So the SCMatrixBlockIter class is used to describe iterators that loop through the elements in a block. That's it. That's the whole thing. Genuinely iconic in its simplicity. 💀

⭐ Version ⭐

Version 2.3.1 — dated Sun Oct 4 2020. A vintage. A classic. A moment in time. 🌸

And that's the whole spread, bestie. Go forth and iterate responsibly. Remember: i() and j() for coordinates, get() to peek, set() to assign, accum() to add, and operator int() to know when to stop. The loop is the journey, fr fr. 💖✨
