#3 gnuplot and output errors

[Anonymous]

I have been using octave workshop for about a month,
and now it suddenly has issues in that it can no longer
plot, and error messages are garbled.

> p2 = x.*xi + y.*yi + z*zi
error: TŒ¥
error: H–\¥
error: (Qδ
error: ‰¥

the issue on that code snippet is the z*zi, which
should be z.*zi . Still, the error is unreadable.

plotting likewise gives:

> plot(x)
error: hD^¥

error: ø@^¥
error: ž•¥
error: ؘ‘¥
error: P˜‘¥

not sure what to do now.
