 Name Edit

Mul M * xyzw - multiply a matrix by a column vector.

Synopsis Edit

vector4 mul(matrix M, vector4 xyzw);
vector4 mul(matrix M, vector3 xyzw);
vector4 mul(matrix M, vector2 xyzw);
vector4 mul(matrix M, vector1 xyzw);

Parameters Edit


Description Edit

Returns the vector result of multiplying a matrix M by a column vector v.

The following are algebrically equal (if not necessarily numerically equal):
