Hmm ... what version are you using? I copied and pasted your commands and they seem fine to me. I'm using BIDMach and BIDMat as of today.

scala> val a = rand(3,4)
a: BIDMat.FMat =

Note: you can put in code in Github comments using the "```" wrap.

I'm seeing this error also, using BIDMach 1.0.3 on OSX
