Functions (matrix.inc)

return	function
VECTOR	Vector(Float:x, Float:y, Float:z);
MATRIX	Matrix(const right[VECTOR], const front[VECTOR], const up[VECTOR], const pos[VECTOR]);
MATRIX	Matrix_Invert(const matrix[MATRIX]);
	Matrix_BuildUp(matrix[MATRIX]);
	Matrix_SetRotation(matrix[MATRIX], Float:rx, Float:ry, Float:rz);
float	Float:Matrix_GetRotationX(const matrix[MATRIX]);
float	Float:Matrix_GetRotationY(const matrix[MATRIX]);
float	Float:Matrix_GetRotationZ(const matrix[MATRIX]);
VECTOR	Matrix_GetRotation(const matrix[MATRIX]);

MATRIX	Matrix_Multiply4x4(const matrix1[MATRIX], const matrix2[MATRIX]);
VECTOR	Matrix_GetOffsetPosition(const matrix[MATRIX], const vector[VECTOR]);
VECTOR	Matrix_GetOffsetRotation(const matrix[MATRIX], const vector[VECTOR], bool:invert = true);

Functions (matrix_example.inc)

return	function
MATRIX	GetVehicleMatrix(vehicleid);
	SetVehicleMatrix(vehicleid, mat[MATRIX]);
VECTOR	GetVehicleRot(vehicleid);
	SetVehicleRot(vehicleid, rot[VECTOR]);
VECTOR	GetVehicleVelocityFrontVector(vehicleid)
	SetVehicleVelocityFrontVector(vehicleid, vec[VECTOR]);

Commands (matrix_example1.pwn)

command	description
/matrix	Start/Stop comparison between matrix, attach and i_quat
/attach	Attach object to vehicle, with predefined offset
/attach_calc_offset	Attach object to vehicle, automatically calc offset
/detach	detach object from vehicle

Commands (matrix_example2.pwn)

command	description
/getvrot	Example of GetVehicleRot
/setvrot	Example of SetVehicleRot
/boost	Example of SetVehicleVelocityFrontVector
/turbo	Same result as /boost

Thank to

IllidanS4 for i_quat, It allowed me to create the Matrix_BuildUp function based on GetVehicleRotationQuatFixed.
Zeex for amx_assembly, it allowed me to create the GetVehicleMatrix and SetVehicleMarix function. Thanks for that.
katursis for Pawn.RakNet, it allowed me to create the SetVehicleMarix function. Thanks for that.
