sc::mat4(3)

✨ NAME ✨

sc::mat4 — okay so this is a section 3 (Library Functions Manual) page, bestie, and it's all about the mat4 class. Think 4x4 matrix energy. 👑

🦋 SYNOPSIS 🦋

💅 Public Member Functions

• mat4 (const vec4 &v0, const vec4 &v1, const vec4 &v2, const vec4 &v3) — build one from four vec4s, one per row-ish situation. 🎀
• mat4 (const double d) — build one from a single double. One number, whole matrix, it's giving minimalism. ✨
• mat4 (const mat4 &m) — copy constructor, the classic. Make a mat4 that's a twin of m. 🫶
• mat4 & operator= (const mat4 &m) — assignment. m's whole vibe becomes yours, and you get *this back. 💖
• mat4 & operator+= (const mat4 &m) — add m onto yourself, return *this. Math but make it in-place. 🔥
• mat4 & operator-= (const mat4 &m) — same deal but subtraction. Take m away from yourself. 💀
• mat4 & operator*= (const double d) — scale yourself by the double d, in place, *this returned. 🌸
• mat4 & operator/= (const double d) — divide yourself by d in place. (No cap, dividing by zero is its own whole situation, be normal about it.) 🍓
• vec4 & operator[] (int i) — index in with an int i, get a vec4 & you can actually mess with. 🧚
• const vec4 & operator[] (int i) const — same index, but the const version, so you get a const vec4 & and cannot touch. Respect the boundaries. ✨
• mat4 transpose () const — hands you the transpose as a fresh mat4. It's const, so it does not touch the original. Iconic behaviour honestly. 🌈
• mat4 inverse () — hands you the inverse. Not const, so yeah, noted. 👀
• mat4 & apply (V_FCT_PTR fct) — runs the function pointer fct over it, returns *this. ⭐

🔒 Protected Attributes

• vec4 v [4] — the actual storage: an array of 4 vec4s. Protected, so it's for the class and its friends, not for randos. 🙈

🫂 Friends

These get to see the protected stuff. Bestie privileges, fr fr.

• mat4 operator- (const mat4 &a) — unary minus. Negate a, get a mat4. 💜
• mat4 operator+ (const mat4 &a, const mat4 &b) — a plus b, brand new mat4. 💖
• mat4 operator- (const mat4 &a, const mat4 &b) — a minus b, brand new mat4. 🌸
• mat4 operator* (const mat4 &a, const mat4 &b) — matrix times matrix. The main character of matrix ops. 👑
• mat4 operator* (const mat4 &a, const double d) — matrix times a double, matrix on the left. ✨
• mat4 operator* (const double d, const mat4 &a) — matrix times a double, but the double is on the left. Order matters, bestie, always. 🔥
• mat4 operator/ (const mat4 &a, const double d) — matrix divided by a double. 🎀
• int operator== (const mat4 &a, const mat4 &b) — equality check, gives you an int. 🦋
• int operator!= (const mat4 &a, const mat4 &b) — the not-equal one, also an int. 💅
• std::ostream & operator<< (std::ostream &s, mat4 &m) — stream m out into s, get s back. ⭐
• std::istream & operator>> (std::istream &s, mat4 &m) — read m in from s, get s back. 🌈
• void swap (mat4 &a, mat4 &b) — swap a and b. Returns nothing, just vibes. 💫
• vec4 operator* (const mat4 &a, const vec4 &v) — matrix times vec4, you get a vec4. 💜
• vec3 operator* (const mat4 &a, const vec3 &v) — matrix times vec3, you get a vec3. Note the type change, that's the whole point. 🧚

And that's the whole page, bestie!! 🎀 This was MPQC, Version 2.3.1, and yes it's the sc::mat4(3) page we've been yapping about this entire time. Go forth and multiply (matrices). Periodt. 💅✨🦋
