Setattr With Matrix Attribute

[visualfx]

Can someone show a working example of setAttr with matrix attribute in python please?

I have tried various things like (with an without the type="matrix")

cmds.setAttr("pSphere1.myMatrix", 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15 , type="matrix")
cmds.setAttr("pSphere1.myMatrix", (0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15) , type="matrix")
cmds.setAttr("pSphere1.myMatrix",[[1.0, 0.0, 0.0, 0.0], [0.0, 1.0, 0.0, 0.0], [0.0, 0.0, 1.0, 0.0], [1.0, 2.0, 3.0, 1.0]] , type="matrix")

mat = cmds.getAttr("pSphere1.testMatrix")
cmds.setAttr("pSphere1.myMatrix", mat , type="matrix")

Nothing seems to work! What's going wrong here??

Thanks.

You can't, not effectively anyway. Use api the functions instead. Like ive said over and over again whoever did the python port killed the idea with silly mistakes like this. The only part in the python that remains stupidity free is the api section. Mainly because the api is harebrained in the first place.

Try getting pymel it makes your life more pythonic.

Mostly no concern here theres really nothing much one can do with matrix attributes in maya anyway
