comment How can I produce an animation in a WPC notebook?
@chrisjj, "local game pad should work there just as does the local mouse" That's easier said than done. Given that the whole interface runs in JavaScript within the confines of a browser it just hasn't access to the same resources as a native program would have. There are some developments in this area, but they all require versions of browsers that are not in use by the general public.

Not that you need it here, but Transpose has a symbol and since you're asking about it: esc-tr-esc after the object you want to transpose, but be beware of its operator precedence.

comment How can I produce an animation in a WPC notebook?
Probably during the private beta, I saw a list of interface elements that were not implemented in WPC or WO. Can't find it anywhere at the moment, but some limitations were pretty intuitive (like not being able to use local gamepads as controllers) given the implementation concept (client/server with considerable delays won't allow for rapid feedback situations needed for many GUI elements).

comment Transform a vector DE into a set of scalar DEs
@chris It was rather difficult to find, but I believe I was alluding to this question.

Though we had a question that showed that this 'improvement ' leads to problems.

You could try setting an upvalue for f using UpSet or TagSet or their delayed versions.

comment How to use ForAll to prove things about functions?
The documentation of Assumptions says: "The assumptions can be equations, inequalities, or domain specifications, or lists or logical combinations of these." I read this as implying ForAll is not included.

comment Dynamic programming: Fibonacci generator
Not sure what you're trying to achieve here (and I'm sure there are better ways) but the problem may lie in your usage of i, j both as symbolic patterns in the second definition of A and as variables with values in the outer loop. It might be that removing the underscores in the second definition resolves the problem.

@m_goldberg given the size of that page it may be good to be a little bit more specific and refer to the actual answer you have in mind.
