Pivot-ing of matrix does not work

@neek: Thank you very much for the quick answer. It works also with V14730.

@Jeff: As you stated, a hint in the help file / manual would have instantly solved the problem. The "good ol' HP49G" even warns you with a beep when CAS wants you to use exact calculation.

It's a shame that the last edition of the manual of a top notch pocket calculator is now SEVEN years old. At the Moravia web site the manual to download is even NINE years old... and no perspective for an update.

Thanks
