You sometimes have to change things for toLua. 

float Matrix[16]; // [row*4 + col]

may work better. Or you could add an interface wrapper, toLua pkg:

typedef float Vertex;
$Vertex* vertex_create() { return malloc(Vertex*16); }
$void vertex_set(Vertex* v,int r,int c) {v[r][c]=v;}
$void vertex_get(Vertex* v,int r,int c) {return v[r][c];}
Vertex* vertex_create();
void vertex_set(Vertex* v,int r,int c);
void vertex_get(Vertex* v,int r,int c);

Just a quick example... hope you get the idea.
