alcvx

Aligned C Vector Extension single-header math library

Status

DONE

• integral scalar types i.e. f32, f64, b8, u8, s8, i8, c8
• arbitrary length vec(t,n) and vec_ext(t,n) power of two types and ALCVX load/cast
• bitceil, isarray, countof, countargs, emptyargs, perm
• OpenMP SIMD linear dot product and sum
• vec(t,n) cross3 product using perm3

TODO

• use bit_ceil and align modes
• array initializer list duplicate for copy assign for types of arbitrary length based on HolyBlackCat/macro_sequence_for
• emulated recursion iteration based on __COUNTER__ for integer sequence
• determinant, laplace expansion and cross4
• levi-civita symbol
• generic n-dim hodge star operator
• motor/rotor/quat and oct/sed/ten types

vec(f32,3) a = {4,2,0};
vec(f32,3) b = dup(a);

Usage

#include <stdlib.h>
#include <stdio.h>
#include <alcvx.h>

int main(int argc, char** argv)
{
     vec3_t src = { 1,2,3 };
    avec3_t dst = ALCVX(src,3);

    dst *= ALCVX(src,3);
    src = dst;
    exit(EXIT_SUCCESS);
