HP50 - Function

[Albert Chan]

I had the same problem in XCas, failed plotting invPsi(x), which uses IFTE to branch to correct guess.
I had to resort to branchless version.

It seems plot is trying hard to compile the function, to speed up plotting.
(it expected to call the function hundreds of time, so simplify the function is reasonable)

When it hit IFTE(condition, x, y), condition part is symbolic, thus unable to simplify further.
It would be nice if plot gives up compiling (if getting stuck), and continued on ...

My guess is the same thing is happening to HP-50g plot.
