This function uses the following formula to compute the returned matrix.

zaxis = normal(Eye - At)
xaxis = normal(cross(Up, zaxis))
yaxis = cross(zaxis, xaxis)

xaxis.x          yaxis.x          zaxis.x       0
xaxis.y          yaxis.y          zaxis.y       0
xaxis.z          yaxis.z          zaxis.z       0
-dot(xaxis, eye)  -dot(yaxis, eye)  -dot(zaxis, eye)  1
