Hi list,
I want to do this:
x = concatenate( (x,x[-1]) )
i.e. append to 1d array x its last element.
However, the only way I managed to do this is:
x = concatenate( (x,array(x[-1],ndmin=1)) )
which is a bit cryptic. (if you remove ndmin, it does not work.)

1. Is there a better way?
2. Could concatenate accept floating point numbers as arguments for convenience?

Thanks in advance,
Nicolas
