sub function CEL definition

March 15, 2009, 00:13

Hi all,

I'm trying to define a rotational domain motion with an unfixed angular velocity, which is a kind of sub function of time. Like, for 0s~10s, W=100t (rad/s), for 10s~20s, W=2000 (rad/s), for 20s~30s, W=2000-200(t-20) (rad/s)

How should I define this angular velocity in terms of CEL?

Thanks for your help in advance.

Regards

Harry

hi Harry,

You can do this as either a CEL expression using the step function or a 1-d interpolation function.
