🌈 DESCRIPTION 🌈

ngl bestie, this is the whole vibe of sc::mat3: she's a matrix, she's got three vec3s stacked up in her protected little heart, and she comes with a full glow-up kit of constructors, operators, and friends who would literally do anything for her.

💅 THE BREAKDOWN 💅

🧚 Constructors & Assignment — her origin story

• mat3 (const vec3 &v0, const vec3 &v1, const vec3 &v2) — build her from three vec3s, like picking out three outfits that slay together.
• mat3 (const double d) — build her from a single double d. one number, main character energy.
• mat3 (const mat3 &m) — copy constructor, she's twin sister to m and they're both iconic.
• mat3 & operator= (const mat3 &m) — assignment. she becomes m. no notes. ✨
• mat3 & operator+= (const mat3 &m) — add m onto her and return the glow-up.
• mat3 & operator-= (const mat3 &m) — subtract m from her, still returning her.
• mat3 & operator*= (const double d) — scale her by d, she stays in the chat.
• mat3 & operator/= (const double d) — divide her by d, returns her again. (no cap, that's just what it does.)

🎀 Element Access — the way that she's indexable

• vec3 & operator[] (int i) — grab the i-th vec3, mutable edition.
• const vec3 & operator[] (int i) const — same i-th vec3, but const and unbothered. 💜

🦋 Transformations — her actual tricks

• mat3 transpose () const — returns her transposed. const because she's not changing for anyone.
• mat3 inverse () — returns her inverse. 🔥
• mat3 & apply (V_FCT_PTR fct) — runs the function pointer fct over her and hands her back to you.

👑 Protected Attributes — the inner circle

• vec3 v [3] — three vec3s named v, protected, doing the actual work behind the scenes. 🙈

🌟 Friends — the whole squad, standing on business

• mat3 operator- (const mat3 &a) — unary minus on a.
• mat3 operator+ (const mat3 &a, const mat3 &b) — a plus b.
• mat3 operator- (const mat3 &a, const mat3 &b) — a minus b.
• mat3 operator* (const mat3 &a, const mat3 &b) — matrix times matrix.
• mat3 operator* (const mat3 &a, const double d) — matrix times scalar d.
• mat3 operator* (const double d, const mat3 &a) — scalar d times matrix, because commutativity is a lie and she said not today.
• mat3 operator/ (const mat3 &a, const double d) — matrix divided by scalar d.
• int operator== (const mat3 &a, const mat3 &b) — are a and b the same? returns an int.
• int operator!= (const mat3 &a, const mat3 &b) — are they not the same? also an int.
• std::ostream & operator<< (std::ostream &s, mat3 &m) — stream m out through s. 🖨️
• std::istream & operator>> (std::istream &s, mat3 &m) — stream m in from s.
• void swap (mat3 &a, mat3 &b) — swap a and b. chaotic, but make it void.
• vec3 operator* (const mat3 &a, const vec3 &v) — matrix times vec3 gives you a vec3.
• vec2 operator* (const mat3 &a, const vec2 &v) — matrix times vec2 gives you a vec2.
