Does anyone know of an example where a class __call__ method takes lists as
input? (With possible symbolic entries, of course.) I'm attempting to follow
the structure of Function_sec (and similar functions) but when I try
sage: var('x')
sage: theta([x,x^2,x^3])
I get the following error:
Traceback (click to the left of this block for traceback)
...
TypeError: descriptor '__call__' requires a
'sage.symbolic.function.Function' object but received a 'list'
So for some reason my function isn't handling the symbolic input. Could
somebody give some further guidance? Maybe a toy function that accepts vector
input?
Thanks,
Chris
