How to setup the view matrix in Codea 4?

In the 3.x we have the function camera() to setup the view matrix:

camera(x, y, z, tx, ty, tz, ax, ay, az)

And we can use the functions of translate(), rotate(), scale() to setup the model matrix, we can use the ortho(), perspective() to setup the projection matrix.

Now in the Codea 4, we have the below functions:

-- for model matrix

-- for projection matrix

-- for view matrix

In Codea 4, the camera is used as a namespace. Do we need a new function, matrix.lookAt() or other name?
