hi,

i am reading Valentin's article just out in V26N5, "going back to the roots".

therein is a complex root solver for the 35s. i was keen to try this out, but i can't get it to work properly on my calculator. i do think that algorithms for complex numbers have been somewhat ignored and this helps to redress that and demonstrate the 35s' comples number features.

since my calculator is new, its likely that i've made some blunder. the second line of code: regx*(1i0->z)->x. what is "regx"? is this just x*(1i0->z)->x or something i've missed?

example 1: works!

example 2: all inputs give 2

example 3: works

example 4: all give 1.3688....

example 5: all give 2.32883 i 0.29914

so basically, im seeing convergence to a favorite root and that is it.

any help? i'll double check again tomorrow for blunders. thanks.
