mDoMtx_YrotS()

void mDoMtx_YrotS	(	Mtx	mtx,
		s16	y )

Sets the given matrix to a rotation transformation around the Y-axis.

This function constructs a 3x4 rotation matrix for rotating around the Y-axis by the specified angle. The matrix is filled directly with cosine and sine values computed from the angle.

The resulting matrix layout is:

• Row 0: cos(y), 0, sin(y), 0
• Row 1: 0, 1, 0, 0
• Row 2: -sin(y), 0, cos(y), 0

Parameters

mtx	The 3x4 matrix to modify (output parameter).
y	The rotation angle as a signed 16-bit integer.
